This patch adds the ability to show a pre-boot splash screen on
Meteor Lake systems using FSP-S.
The patch calls into `fsp_convert_bmp_to_gop_blt()` when the
`BMP_LOGO` config is enabled. This function converts a BMP
file to a BLT buffer, which is then used by FSP-S to render the splash
screen.
Additionally, increase the heap size (malloc'able size) upto 512KB
(when BMP_LOGO config is enabled) to accommodate high
resolution logo file.

This patch adds an API to convert BMP images into GOP BLT buffers for
Intel FSP-S. This is required to display the OEM splash screen at
pre-boot phase.
Previously, Intel FSP-S had provision to consume the *.BMP file as is.
However, starting with the Alder Lake platform, Intel FSP has dropped
this conversion logic and expects the boot firmware to pass the BLT
buffer directly.
This patch implements the conversion logic in coreboot.

This patch adds BMP image header and BLT header macros in
`efi_datatype.h` to implement a converter inside coreboot FSP 2.0
driver that converts any input *.BMP image into the BLT buffer.
The output BLT buffer is used by FSP-S to render any pre-boot display.
Added `Bmp.h` and `GraphicsOutput.h` files for `UDK base >= 2017`,
as these files were added with the UDK version 2017.
Note: BLT in UEFI BMP implementation stands for `Bit-block transfer`.
It is a method of copying graphis data (specifically images and fonts)
from one location to another (framebuffer), where the data is stored
in blocks of bits.

Intel requires that all enabled PCIe PCH ports have a CLK_REQ signal
connected. The CLK_REQ is used to wake the silicon when link entered
L1 link-state. L1 link-state is also entered on PCI-PM D3, even with
ASPM L1 disabled. When no CLK_REQ signal is used, for example when
it's using a free running clock the silicon will never wake from L1
link state. This will trigger a MCE.
Starting with FSP MR4 the UPD 'PchPcieClockGating' allows to work
around this issue by disabling ClockGating. Disabling ClockGating
should be avoided as the silicon draws more power when it is idle.
TEST: Verified on two boards, one with missing CLK_REQ on a PCH
root port, that the code does the right decision to disable
UPD PchPcieClockGating and PchPciePowerGating when necessary.

With reference to the Picasso PPR 55570 Rev 3.18, LegacyIoEn bit is 0 on
reset and setting it will enable the decoding of the following legacy IO
ports:
0x20, 0x21, 0xA0, 0xA1 (PIC);
0x40, 0x41, 0x42, 0x43, 0x61 (8254 timer);
0x70, 0x71, 0x72, 0x73 (RTC);
0x92.
Verstage does not use those legacy IO ports. Also newer SoCs like
Phoenix do not support Legacy I/O registers to access Power Management
registers and accessing them from PSP verstage causes a hang. Hence
enable legacy IO only on platforms that support it.

Merlin was the name for the open-source variant of the EC. It
ended up getting entirely rewritten to work with SDCC, and is
currently being used on starbook/adl. The source code isn't
available at the time of this commit due to some old ITE XLT
code being used.
Add the latest version of the code, replacing the old code, so
the boards can be migrated over.

The use of a separate _PRW is not necessary when the _CRS interrupt
already has the Wake flag set (as these all do). Additionally, Windows
does not allow the use of a gpioint for the _PRW source, which results
in an ACPI_BIOS_ERROR BSOD.
Since ChromeOS builds for CYAN devices use an older kernel and may not
make use of _CRS interrupt Wake flag, keep the _PRW around when
CONFIG_CHROMEOS is selected.

Prior to commit d1c0f958d1 ("acpi: Call acpi_fill_ssdt() only for
enabled devices"), uart_inject_ssdt() was used to set the ACPI status
(_STA) for both enabled and disabled devices. The aforementioned commit
limited it to being called only on enabled devices, which left disabled
devices without any _STA method at all -- which the OS assumes means
that the device is present and enabled.
To fix this, create the _STA method in the UART asl code for each port,
and set the return value to a name variable (STAT) which defaults to
0 (not present/disabled). Then, have uart_inject_ssdt() set STAT to
present and enabled (0xF) for UARTs actually present on the board.
TEST=build/boot google/skyrim (frostflow), dump ACPI tables, and verify
that _STA returns 0xF only for UARTs enabled in devicetree.
