Description
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: ipq8074: dont disable gcc_sleep_clk_src
Once the usb sleep clocks are disabled, clock framework is trying to
disable the sleep clock source also.
However, it seems that it cannot be disabled and trying to do so produces:

So, add CLK_IS_CRITICAL flag to the clock so that the kernel won't try
to disable the sleep clock.
