Blackfin: cpufreq: use a constant latency
PLL_LOCKCNT applies only to the PLL programming sequence which does not
apply to core and system clock dividers. Writes to PLL_DIV to change the
CSEL/SSEL dividers take effect immediately.
There is still overhead in software in writing the new dividers, so just
use a value of 50us as this should be good enough.
