[Matt Papageorge (Code Review)]

Hello build bot (Jenkins), Raul Rangel, Martin Roth, Furquan Shaikh, Marshall Dawson, Aaron Durbin, Felix Held,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/42829

to look at the new patch set (#4).

Change subject: soc/amd/picasso/sb: Gate FCH AL2AHB clocks
......................................................................

soc/amd/picasso/sb: Gate FCH AL2AHB clocks

Gate the A-Link to AHB Bridge clocks to save power. These
are internal clocks and are unneeded for Raven/Picasso.
This was previously performed within the AGESA FSP but this
change relocates it into coreboot.

BUG=b:154144239
TEST=Check AL2AHB clock gate bits at the end of POST before and
after change with HDT.
