d2d5e44a67 acpi_device: Replace polarity with active_low in acpi_gpio for GpioIo
As per ACPI spec, GpioIo does not have any polarity associated with
it. Linux kernel uses `active_low` argument within GPIO _DSD property
to allow BIOS to indicate if the corresponding GPIO should be treated
as active low. Thus, if GPIO has active high polarity or if it does
not have any polarity associated with it, then the `active_low`
argument is supposed to be set to 0.

Having a `polarity` field in acpi_gpio seems confusing because GPIOs
might not always have polarity associated with them. Example, in case
of DMIC-select GPIO where 0 means select DMIC0 and 1 means select
DMIC1, there is no polarity associated with the GPIO. Thus, it would
be clearer for mainboard to use macros without having to specify a
particular polarity. In order to enable mainboards to provide GPIO
information without polarity for GpioIo usage, this change also adds
`ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

fc57d6c4c2 cpu/x86/lapic: Support x86_64 and clean up code
Most LAPIC registers are 32bit, and thus the use of long is valid on
x86_32, however it doesn't work on x86_64.

* Don't use long as it is 64bit on x86_64, which breaks interrupts
  in QEMU and thus SeaBIOS wouldn't time out the boot menu
* Get rid of unused defines
* Get rid of unused atomic xchg code

Tested on QEMU Q35 with x86_64 enabled: Interrupts work again.
Tested on QEMU Q35 with x86_32 enabled: Interrupts are still working.

When adding XIP stages on x86, the -P parameter was used to
pass a page size that covers the entire file to add. The same
can now be achieved with --pow2page and we no longer need to
define a static Konfig for the purpose.

TEST: Build asus/p2b and lenovo/x60 with "--pow2page -v -v" and
inspect the generated make.log files. The effective pagesize is
reduced from 64kB to 16kB for asus/p2b giving more freedom
for the stage placement inside CBFS. Pagesize remained at 64kB
for lenovo/x60.

b8c473e32f amd/00730F01: Clean the Microcode updating
According to the comments of
https://review.coreboot.org/c/coreboot/+/41719
, which is about Microcode patch for amd/picasso.
Change the code with the same way.

The changes include:
1. combine the microcode_xxx.c and update_microcode.c
   into one source.
2. Redefine the microcode updating function to eliminate
   the parameter. Get the revision ID in the black box.
   Reduce the depth of function calls.
3. Get the revision ID by bitwise calculation instead of
   lookup table.
4. Reduce the confusing type casts.
5. Squash some lines.

We do not change the way it used to be. The code assume
only one microcode is integrated in CBFS. If needed in future,
41719 is the example of integrating multiple binaries.

And, 41719 depends on the definition in this patch.

84fac41d35 acpi: Accomodate non-standard UUIDs in device properties
There have been changes to the way device properties are supported
in Linux[1] and Windows[2] which add flexibilty:

- non-standard UUIDs can be used instead of only ACPI_DP_UUID
- support for multiple different packages within the _DSD that
associate different properties with unique UUIDs.

To handle this I extracted the part that does the write of UUID and
properties to a separate function and defined a new PACKAGE type
which has the custom UUID as a name and can be used the same way that
child properties are today.

For example a PCIe root port for a USB4 port has a standard property
indicating the USB4 reference, and then two custom properties which
are defined for different attributes.

Example code:

/* Create property table */
acpi_dp *dsd = acpi_dp_new_table("_DSD");
acpi_dp_add_reference(dsd, "usb4-port", usb4_path);

/* Add package for hotplug */
acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4");
acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1);
acpi_dp_add_package(dsd, pkg);

/* Add package for external port info */
pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389");
acpi_dp_add_integer(pkg, "ExternalFacingPort", 1);
acpi_dp_add_package(dsd, pkg);

/* Write all properties */
acpi_dp_write(dsd);

Resulting ACPI:

Scope (\_SB.PCI0.TRP0)
{
    Name (_DSD, Package ()
    {
        ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
        Package ()
        {
            Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA }
        },

        ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
        Package ()
        {
            Package () { "HotPlugSupportInD3", One }
        },

        ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"),
        Package ()
        {
            Package () { "ExternalFacingPort", One },
        }
    })

36e6c6f8d2 fw_config: Add firmware configuration interface
This change introduces a new top-level interface for interacting with a
bitmask providing firmware configuration information.

This is motivated by Chromebook mainboards that need to support multiple
different configurations at runtime with the same BIOS.  In these
devices the Embedded Controller provides a bitmask that can be broken
down into different fields and each field can then be broken down into
different options.

The firmware configuration value could also be stored in CBFS and this
interface will look in CBFS first to allow the Embedded Controller value
to be overridden.

The firmware configuration interface is intended to easily integrate
into devicetree.cb and lead to less code duplication for new mainboards
that make use of this feature.

BUG=b:147462631
TEST=this provides a new interface that is tested in subsequent commits
