Clock framework will enable those clocks registered
with CLK_IS_CRITICAL flag, so no need to have
clks_init_on array during clock initialization now.

ARM clock is busy divider type which has the
CLK_IS_CRITICAL flag set by default when registered.

IPG clock has no clock gate and its parent AHB clock
is busy divider type, so no need to add CLK_IS_CRITICAL
flag for IPG clock.
