Since the OS provides its own driver for the I2C controller it can
choose to use a bus speed other than the one used at coreboot runtime.
In this case it would be good to provide a way how the needed bus
timings are communicated to the OS, since these are very board-specific
and there is no way that the OS can know them other than read the
appropriate ACPI reported timings.
This patch adds some code to report additional bus speed timings if
there are some defined in the devicetree.

This patch adds the ACPI hardware error source table (HEST) support.
This involves a few different parts: (1) The ACPI HEST table which is filled
with the appropriate fields (2) Reserved memory which is used by runtime
SW to provide error information. OS will not accept a HEST table with
this memory set to 0.
The ASL code to enable APEI bit will be submitted in a separate patch.
Tested on DeltaLake mainboard with following options enabled
SOC_INTEL_XEON_RAS
After boot to Linux, the following will show in dmesg:
HEST: Table parsing has been initialized

There are cases where the RTC_VRT bit in register D stays set after a
power failure while the real date and time registers can contain rubbish
values (can happen when RTC is not buffered). If we do not detect this
invalid date and/or time here and keep it, Linux will use these bad
values for the initial timekeeper init. This in turn can lead to dates
before 1970 in user land which can break a lot assumptions.
To fix this, check date and time sanity when the RTC is initialized and
reset the values if needed.

Already released Linux versions did not have the needed ACPI-extension

older Linux will not be able to use this device as it will be claimed by
the PNP-drivers. As there is no way to avoid that an older Linux kernel
meets a newer coreboot in the field, we need to disable the ACPI
support for the RTC for the mc_apl-based mainboards.

In commit b64db833d6 a basic ACPI support was added to the driver.
With this support an SSDT-entry is created for this RTC and it is now
visible to the OS via ACPI. In Linux the PNP-devices, which are
reported over ACPI, are scanned rather early and if the entry is found,
the device is claimed even if there is no driver available yet.
In this case, when the native RTC-driver without ACPI-support is loaded
and tries to register this device, the RTC is already blocked by the
PNP-drivers and cannot be used anymore. This leads to a non-usable RTC
on kernels where the needed ACPI-extension is not yet merged into the
RTC driver.
This patch provides a way to disable the ACPI-support for the RTC if
needed.

As `size_t` is defined as `long unsigned int` in i386-elf (32-bit), the
length modifier `l` matches there. With x86_64-elf/x86_64-linux-gnu

typedef unsigned long uintptr_t;
As `size_t` is defined as `long unsigned int` in i386-elf (32-bit), the
length modifier `z` matches there. With x86_64-elf/x86_64-linux-gnu

the length modifier `l` to make the code more readable.
