soc/amd/common/block/espi: Explicitly assert PLTRST#

PLTRST# is currently asserted and latched when eSPI_RST# gets asserted.
If eSPI_RST# isn't used on a platform or it doesn't properly assert
in all cases, then PLTRST# will never be asserted. This could result in
the AP and EC being out of sync.

BUG=b:188188172, b:188935533
TEST=Warm reset guybrush with partial #22 rework. Verify that peripheral
channel is correctly reset.
