This change adds details about the memory map windows to translate

decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

This change enables support for a custom boot media device in fast SPI
controller driver if the platform supports additional decode window
for mapping BIOS regions greater than 16MiB. Following new Kconfigs
are added:
1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate
support for extended BIOS window.
2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the base address of the host space that is
reserved for mapping the extended window.
3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the size of the host space reserved for
mapping extended window.
If platform indicates support for extended BIOS decode window,
cbfstool add command is provided additional parameters for the decode
window using --ext-win-base and --ext-win-size.
It is the responsibility of the mainboard fmap author to ensure that
the sections in the BIOS region do not cross 16MiB boundary as the
host space windows are not contiguous. This change adds a build time
check to ensure no sections in FMAP cross the 16MiB boundary.
Even though the platform supports extended window, it depends upon the
size of BIOS region (which in turn depends on SPI flash size) whether
and how much of the additional window is utilized at runtime. This
change also provides helper functions for rest of the coreboot
components to query how much of the extended window is actually
utilized.

This change updates the translated region device (xlate_region_dev) to
support multiple translation windows from the 1st address space to
2nd address space. The address spaces described by the translation
windows can be non-contiguous in both spaces. This is required so that
newer x86 platforms can describe memory mapping of SPI flash into
multiple decode windows in order to support greater than 16MiB of
memory mapped space.
Since the windows can be non-contiguous, it introduces new
restrictions on the region device ops - any operation performed on the
translated region device is limited to only 1 window at a time. This
restriction is primarily because of the mmap operation. The caller
expects that the memory mapped space is contiguous, however, that is
not true anymore. Thus, even though the other operations (readat,
writeat, eraseat) can be updated to translate into multiple operations
one for each access device, all operations across multiple windows are
prohibited for the sake of consistency.
It is the responsibility of the platform to ensure that any section
that is operated on using the translated region device does not span
multiple windows in the fmap description.
One additional difference in behavior is xlate_region_device does not
perform any action in munmap call. This is because it does not keep
track of the access device that was used to service the mmap
request. Currently, xlate_region_device is used only by memory mapped
boot media on the backend. So, not doing unmap is fine. If this needs
to be changed in the future, xlate_region_device will have to accept a
pre-allocated space from the caller to keep track of all mapping
requests.

Especially server boards, like the Supermicro X11SSM-F, often have a NMI
button and NMI functionality that can be triggered via IPMI. The purpose
of this is to cause the OS to create a system crashdump from a hang
system or for debugging.
Add code for enabling NMI interrupts on GPIOs configured with
PAD_CFG_GPI_NMI. The enabling mechanism is the same as SMI, so the SMI
function was copied and adapted. The `pad_community` struct gained two
variables for the registers.
Also register the NMI for LINT1 in the MADT in accordance to ACPI spec.
Test: Linux detects the NMI correctly in dmesg:
[ 0.053734] ACPI: LAPIC_NMI (acpi_id[0xff] high edge lint[0x1])
