[coreboot-gerrit] Change in coreboot[master]: mb/google/hatch: Program gpio clk power gating settings in SPI0 PS3/PS0

[Kane Chen (Code Review)]

Hello Subrata Banik, Aamir Bohra, build bot (Jenkins), Furquan Shaikh,

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

https://review.coreboot.org/c/coreboot/+/37865

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

Change subject: mb/google/hatch: Program gpio clk power gating settings in SPI0 PS3/PS0

mb/google/hatch: Program gpio clk power gating settings in SPI0 PS3/PS0

With PchPmSlpS0Vm075VSupport FSP UPD set, SoC requires gpio clk to be
power gated, but when gpio clk is power gated, it requires longer interrupt
assertion from device.

This change fixes runtime s0ix with PchPmSlpS0Vm075VSupport set.

And it sets gpio clk power gating settings in SPIO PS0/PS3 so that
cr50 doesn't need longer interrupt assertion.

BUG=:141831197
TEST=run suspend/stress, cold reset tests 2500 cycles and
     check no irq missed in kernel msg
