mb/google/volteer: Fix S0i3 regression

Keeping the PM timer enabled will disqualify an ADL system from entering
S0i3, and will also cause an increase in power during suspend states.
The PM timer is not required for brya boards, therefore disabling it.
Fixes: 0e90580 (soc/intel: transition full control over PM Timer from
FSP to coreboot)

This mirrors an identical commit for google/brya: 1ce0f3aab72d
("mb/google/brya: Fix S0i3 regression")

TEST=Boot Linx on google/drobit, verify S0i3 counter incrementing after
exiting S0ix suspend states.
