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.
