[PATCH 4/5] clk: qcom: gcc-msm8996: Mark gcc_mmss_noc_cfg_ahb_clk as a critical clock

we have gcc_mmss_noc_cfg_ahb_clk marked with a CLK_IGNORE_UNUSED. While
this can prevent it from being disabled while its unused, it does not
prevent it from being disabled when a child derived from the clock calls
an explicit enable/disable.
Mark this with a CLK_IS_CRITICAL and remove the CLK_IGNORE_UNUSED flag
so its never disabled.
