[ARM] twd: Allow twd rescaling to match cpu frequency
The clock to the ARM TWD local timer scales with the cpu
frequency. To allow the cpu frequency to change while
maintaining a constant TWD frequency, pick a lower target
frequency for the TWD and use the prescaler to divide down
to the closest lower frequency.
This patch provides a new initialization function that takes
a target TWD frequency and the relation between the cpu
clock and the TWD clock, required to be an integer divider
>= 2 by the ARM spec. It also provides a function to be
called from cpufreq drivers to set the prescaler whenever
the cpu frequency changes.
Also fixes a typo in the printk of the calibrated frequency.
