ipq8084: provide monotonic us timer
This service is required by various coreboot code modules. It looks
like the 8064 SOC does not provide anything better than a 32 KHz free

BUG=chrome-os-partner:27784
TEST=manual
. with the rest of the patches applied AP148 boots all the way to
trying to start the payload.
