clk: imx7d: remove CLK_IS_CRITICAL flag for arm_a7_root_clk
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 pll_arm_main_bypass 1 1 0 792000000 0 pll_arm_main_clk 1 1 0 792000000 0 arm_a7_src 1 1 0 792000000 0 arm_a7_cg 1 1 0 792000000 0 arm_a7_div 1 1 0 792000000 0 arm_a7_root_clk 1 1 0 792000000 0 arm 1 1 0 792000000 Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
