The CONNECT X300 uses the PMC clock for on-board components and gets
stuck during boot if the clock is disabled. Therefore, add this
device to the critical systems list.
Tested on CONNECT X300.
Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")

Thank you for your patch!
Can you be more specific about the clock (which one? For example plt2)
and if possible type of hardware IP which is connected to it (for
example, Realtek Ethernet)?

I'm sorry, I don't have more detailed information. I only identified the bug
by git bisect.
