arm: tegra: clock: Reading APB bus before disabling clock
It may be possible that write operation on apb bus does not get
complete before disabling clock if the clock is disabled just after
the write on apb bus.
To have proper sequence of operation, it is require to read back the
apb bus to make sure the write operation is completed.
