x86: Increase time out for parking APs to 250ms
Change f43adf0 (intel/common/block/cpu: Change post_cpus_init after
BS_DEV RESOURCES) moved post_cpus_init to BS_OS_RESUME for S3
path. This results in BSP timing out waiting for APs to be
parked. This change increases the time out value for APs to be parked
to 250ms. This value was chosen after running suspend-resume stress
test and capturing the maximum time taken for APs to be parked for
100 iterations. Typical values observed were ~150ms. Maximum value
observed was 152ms.
BUG=b:76442753
TEST=Verified for 100 iterations that suspend-resume does not run into
any AP park time out.
