mb/google/brya: Enable asynchronous End-Of-Post
Set the `SOC_INTEL_CSE_SEND_EOP_ASYNC' flag to request End-Of-Post
right after PCI enumeration and handle the command response at
`BS_PAYLOAD_BOOT'.
With these settings we have observed a boot time reduction of about 20
to 30 ms on brya0.
BUG=b:268546941
BRANCH=firmware-brya-14505.B
TEST=Tests on brya0 with `SOC_INTEL_CSE_SEND_EOP_ASYNC' show
End-Of-Post after PCI initialization and EOP message received at
`BS_PAYLOAD_BOOT'.
