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
    running counter (it is used in u-boot for us timer as well). Let's use
    this for now.

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.
