soc/amd/picasso/acpi,mb/{zork,mandolin}: Stop clearing PciExpWakeStatus
The kernel already clears this: https://source.chromium.org/chromiumos/chromiumos/codesearch/+/master:src/third_party/kernel/v5.4/drivers/acpi/acpica/hwregs.c;l=390
No reason to have the firmware do it as well.
BUG=b:153001807, b:154756391
TEST=Build Trembyle, boot, suspend, and resume and didn't see any ACPI
errors.
