This change adds a helper function `pcie_rp_enable_mask()` that
returns a 32-bit mask indicating the status (enabled/disabled) of PCIe
root ports (in the groups table) as configured by the mainboard in the
device tree.
With this helper function, SoC chip config does not need to add
another `PcieRpEnable[]` config to identify what root ports are
enabled.

Add support for the Intel LPIT table to support reading Low Power Idle
Residency counters by the OS. On platforms supporting S0ix sleep states
there can be two types of residencies:
* CPU package PC10 residency counter (read from MSR via FFH interface)
* PCH SLP_S0 assertion residency counter (read via memory mapped
interface)
With presence of one or both of these counters in the LPIT table, Linux
dynamically adds the corresponding attributes to the cpuidle sysfs
interface, that can be used to read the residency timers:
* /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
* /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
The code in src/acpi implements generic LPIT support. Each SoC or
platform has to implement `acpi_fill_lpit` to fill the table with
platform-specific LPI state entries. This is done in this change for
soc/intel/common, while being added as its own compilation unit, so SoCs
not yet using common acpi code (like Skylake) can use it, too.

Drop the support for the Intel Cannon Lake SoC for various reasons:
* Most people can't use coreboot on Cannon Lake, since the required FSP
binaries aren't publicly available. Given that FSP binaries for several
newer platforms have been released, it's very unlikely that Cannon Lake
FSP will ever be released.
* It seems there is no interest in this, since the reference mainboard
is the only available mainboard in tree.
Also, remove the related reference mainboard intel/cannonlake_rvp and
its FSP headers in intel/fsp2_0/cannonlake.

This change updates various uart_* functions to use simple(_s_)
variants of PCI functions. This is done for a few reasons:
* __SIMPLE_DEVICE__ check can be dropped since the same data type can
be used in early stages and ramstage.
* Removes the requirement on early stage to walk the device tree to
get access to the device structure. This allows linker-based device
tree optimizations for early stages.
As part of this change, uart_get_device() is refactored and a new
function uart_console_get_devfn() is added which returns pci_devfn_t
in MMCONF format. It is then used directly by the _s_ variants of PCI
functions.

Prevent the FSP from writing its default SVID SDID values of 8086:7270
for internal devices as this locks most of the registers. Allows the
subsystemid values set in devicetree to be used.
A description of this SSID table override behavior, along with example
code, is provided in the TigerLake FSP Integration Guide, section
15.178 ("SI_CONFIG Struct Reference").
The xHCI and HDA devices have RW/L registers rather than RW/O registers.
They can be written to multiple times but cannot be modified after
being locked, which happens during FspSiliconInit. Because coreboot
populates subsystem IDs after SiliconInit, these devices specifically
must be written beforehand or will otherwise be locked with their
default values of 0:0.
Tested by checking lspci output on System76 galp3-c (WHL), oryp5 (CFL),
and oryp6 (CML).

which select INTEL_GMA_ACPI. Rework brightness level includes and
platform-level asl files to avoid duplicate device definition for GFX0.
Include gfx.asl for Skylake/Kabylake, since all other soc/intel/common
platforms already do. Adjust mb/51nb/x210 to prevent device redefinition.
Some OSes (e.g. Windows, MacOS) require/prefer the ACPI device for
the IGD to exist, even if ACPI brightness controls are not utilized.
This change adds a GFX0 ACPI device for all boards whose platforms
select INTEL_GMA_ACPI without requiring non-functional brightness
controls to be added at the board level.
