Jason Liu 766f6d2a32 ARM: 7778/1: smp_twd: twd_update_frequency need be run on all online CPUs
commit cbbe6f82b4 upstream.

When the local timer freq changed, the twd_update_frequency function
should be run all the CPUs include itself, otherwise, the twd freq will
not get updated and the local timer will not run correcttly.

smp_call_function will run functions on all other CPUs, but not include
himself, this is not correct,use on_each_cpu instead to fix this issue.
