Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Jason Nien, Matt DeVillier, Martin Roth, Fred Reitberger, Karthik Ramasubramanian, Felix Held,

to look at the new patch set (#6).

Change subject: soc/amd/mendocino: Enable GPP clk req disabling for disabled devices

soc/amd/mendocino: Enable GPP clk req disabling for disabled devices

Enable GPP clk req disabling for disabled PCIe devices. If a clk req
line is enabled for a PCIe device that is not actually present and
enabled then the L1SS could get confused and cause issues with
suspending the SoC.

BUG=b:250009974
TEST=Ran on skyrim proto device, verified that clk reqs are set
appropriately
