mb/google/rex: 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
100ms on google/rex.
TEST=Tests on google/rex with `SOC_INTEL_CSE_SEND_EOP_ASYNC' show
End-Of-Post after PCI initialization and EOP message received at
`BS_PAYLOAD_BOOT'.
