clk: qcom: Add QCOM_CLK_BOOT_CRITICAL flag

Browse Source 
Some clks are critical and required to be on during probe to sync-state,
and also later needs to controlled by consumers. Add QCOM_CLK_BOOT_CRITICAL
flag to achieve turning on clk during probe and also register wih clk
framework so consumers can control after boot.
