QCLK means "quadrature clock", and is equivalent to one half of a full
clock cycle (tCK). Fix the comment. The `QCLK_PI` value is still valid.

Use global variables to provide mainboard USB settings, and have the
northbridge code copy it into the `pei_data` struct. For now.
To minimize diffstat noise, this patch does not reindent the now-global
mainboard USB configuration arrays. This is cleaned up in a follow-up.

Using MCHBAR32_AND_OR() in these two cases changes the order of
additions slightly. Originally, the MCHBAR offset and the base
register offset (0x5a4/0x5b4) were added first. Due to the added
parentheses in the register macros, now the complete register
offset is calculated first and then added to MCHBAR. Associativity
tells us that this doesn't change the result.
Changes in the resulting binary were verified manually on the
object file.

The RCOMP data group is special and is programmed differently. Prepare
to simplify the code by programming it outside of the loop. Subsequent
commits will simplify the logic even further, then clean up cosmetics.
The special DDR3 case in the loop overwrites the command group strength
multiplier value. It doesn't need to be programmed for each RCOMP group.
Add a comment to justify not programming this register while programming
the settings for the RCOMP data group.

MRC uses an incorrect mask when programming this register, but the reset
default value is zero and it is only programmed once. As it makes no
difference, we can safely use the correct mask. Document this difference
in a comment to indicate the deviation from MRC behavior is intentional.
The default value for this register was dumped from Asus P5QL PRO.

It was commented that the need for the delay was mainly related
to external displays and only with VBIOS execution. Move the
delay such that it is done only when we actually need to execute
the VBIOS aka option rom.
A delay is currently only defined for librem/purism_bdw in
its Kconfig. As the description of the issue sounds like it
would equally happen on other platforms when VBIOS is involved,
promote the Kconfig visible option to global scope.
