clk: qcom: smd-rpm: Set XO rate and CLK_IS_CRITICAL on PCNoC

On all supported SoCs to date, the PCNoC (a.k.a CNoC_PERIPH) clock must
be always-on as long as the APSS is online and only has to run
at 19.2 MHz. Define it to be as such in the ACTIVE domain.

Some SoCs use that clock for bus scaling, while others just need it for
reaching the hardware. This commit will hurt neither.
