    libpayload: Generalize and redistribute timekeeping code
    The timekeeping code in libpayload was dependent on rdtsc, and when it was
    split up by arch, that code was duplicated even though it was mostly the same.
    This change factors out actually reading the count from the timer and the
    speed of the timer and puts the definitions of ndelay, udelay, mdelay and
    delay into generic code. Then, in x86, the timer_hz and timer_get_raw_value
    functions which used to be in depthcharge were moved over to libpayload's
    arch/x86/timer.c. In ARM where there isn't a single, canonical timer, those
    functions are omitted with the intention that they'll be implemented by a
    specific timer driver chosen elsewhere.
