Add downgrade support for CSE RW firmware.
When CSE FW is downgraded, CSE may get into data compatibility issues.
To avoid such issues, coreboot sends DATA CLEAR HECI command to CSE to
clear CSE run time data on proactive basis during a downgrade and
when CSE indicates a data mismatch error through GET_BOOT_PARTITION_INFO.

Since Puff uses CSE Lite SKU that supports in-field CSME
updates an additional reset is triggered when jmp from RO
to RW during boot. However this reset is not detected by
the cr50 running older firmware because the strapping
configuration for EFS2 uses PLT_RST_L to assert to cr50
that a AP reset occured. The older cr50 firmware
version of 0.0.22 only monitors AP resets via SYS_RESET_L
and hence never detects the reset.
To mitigate the issue above a modified reset sequence is
required to be performed to signal the reset occured and
hence a board-specific cse_board_reset() strong symbol is
provided to modify the flow accordingly.

According to the IT8728F datasheet it is possible to add an extra delay
between 3VSBSW# being set and PWRGD3 being set during resume from
Suspend-to-RAM. This is enabled in the special function selection
register, the default being 0.
This is also useful for the IT8720F although this chip does not have the
PWRGD3 output. On the corresponding pin it has PWROK2, which the setting
then seems to apply to.
The datasheet for the IT8720F marks the corresponding bit as reserved,
but the vendor BIOS of an Acer Aspire M3800 sets it anyway. Without
setting the bit, coreboot fails to resume from S3. Oscilloscope
measurements have shown that setting the bit increases the delay between
3VSBSW# being set and PWROK2 being set from around 1 us to 140 ms. The
actual use of PWROK2 on the board design is unclear - the only
destination it seems to reach is a pin header near the SuperIO marked as
"GPIO1".

The Linux kenerl driver for AMD gpu currently has a floor
value of 12 for brightness settings (AMDGPU_DM_DEFAULT_MIN_BACKLIGHT).
AMD indicates they did this because they were concerned with certain
panels flickering at lower backlight values. However, for unaffected
panels it's desirable to be able to have the panel "turn off" at
the lowest backlight setting. The only way to do that is to provide
ATIF bindings that indicate backlight range.
Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full
range for the backlight setting. If needed, this path can be built upon
for fuller support, but for the time being this is the only thing
necessary to make the backlight be full range.

With CSE-lite enabled, we were going through the lengthy memory
training procedure twice on the first power-on boot or after full BIOS
SPI flash update. This moves the global reset performed to achieve the
CSE-lite RO to RW reboot to a later boot phase so that it happens
after the memory training data has been written to the MRC cache. Now,
the 2nd (and subsequent) reboot can utilize the memory training data
established during the 1st boot.
This reduces the first boot time by about 20s on a 16GB system.
Looking at the timing stats form cbmem, the normal boot penalty is
about 300ms - mostly attributed to running FspSiliconInit a 2nd
time. We will get this time back when the mrc_cache refactoring effort
lands (cb:44196, et. al).

For Volteer (and future Tiger Lake boards) we can enable mode S0i3.4
only if we know that the Cr50 is generating 100us interrupt pulses.
We have to do so, because the SoC is not guaranteed to detect pulses
shorter than 100us in S0i3.4 substate.
A new Kconfig setting CR50_USE_LONG_INTERRUPT_PULSES controls new code
running in verstage, which will program a new Cr50 register, provided that
Cr50 firmware is new enough to support the register.
