clk: imx7d: remove CLK_IS_CRITICAL flag for arm_a7_root_clk

2018-10-17T15:26:04+00:00

i.MX7D uses virtual cpu clock of "arm" clock to be child clock
of "arm_a7_root_clk" and it is with CLK_IS_CRITICAL flag set, so
no need to add CLK_IS_CRITICAL flag for keeping "arm_a7_root_clk"
use count correct, latest clock tree is as below in clk_summary:

pll_arm_main                         1        1        0   792000000          0
