Add support to override SPI fast speeds based on board version from both
bootblock and verstage. Overrides apply for Guybrush only and SPI speed
is overridden from 66 MHz to 100 MHz starting board version 4. This will
help to improve the boot time on board version by ~60 ms and still allow
the old boards to boot with 66 MHz.

Fizz's USB ACPI code is intended to allow the OS to control port
charging power, but since Fizz's ports are dumb (vs smart), it
controls power to the port itself. The end result is that active
ports become disabled when rebooting from Windows (10/11), and
power is not restored until the device is powered down (a warm
reboot is not sufficient).
Subsequent Chromebox models (eg, Puff-based variants) don't bother
with EC-controlled USB port power, so just drop it since it's
problematic and provides no benefit.
Test: boot Windows 10/11, reboot, observe active USB ports still
functional (eg, USB KB still works)

This commit fixes writing to XML files with JUNIT_OUTPUT=y, but had to
sacrifice path in test name, as it was causing a lot of problems
(because CMocka does not know, how to write multiple test groups to one

On this mainboard there is a legacy PCI device, which is connected to
the PCIe root port via a PCIe-2-PCI bridge. This device only supports
legacy interrupt routing. For this reason, we have to adjust the PIR8
register (0x3150) which is responsible for PCIe device 25h. The bridge
is connected to PCIe root port 7.
The following routing is required:
INTA#->PIRQC#, INTB#->PIRQD#, INTC#->PIRQA#, INTD#-> PIRQB#
TEST:
- Boot into system software

This mainboard uses an eSPI-to-LPC bridge for console output. For this
reason, the internal LPSS UART must be disabled.

This board has the RTC RX6110SA connected to the I2C2 instead of SMBus
as in mc_ehl1. Set the bus speed for I2C2 to 100 kHz, since this RTC
only supports the standard speed.
TEST:
- Console Log shows no errors for RX6110SA during I2C2 init
- Finalize device for I2C 00:32 shows correct date and time

Since this variant uses different DDR4 devices compared to mc_ehl1 in a
memory down configuration, the SPD data file must be adapted.
In a first configuration we use Micron MT53D512M32D2NP modules.
Following values were adjusted according to this board characteristic
and with help of Serial Presence Detect (SPD) for LPDDR3 and LPDDR4
SDRAM Modules JEDEC Spec and the Specification for this Micron modules
itself:
- SPD Byte 4 - only 4Gb density instead of 8Gb for mc_ehl1
- SPD Byte 5 - different Row and Column Address Bits
- SPD Byte 29/30 - 4Gb LPDDR4 needs 130ns tRFCab
- SPD Byte 31/32 - 4Gb LPDDR4 needs 60ns tRFCpb
