clk: imx6sl: remove clks_init_on array
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.
