soc/intel/common/acpi: Support on/off PCIe CLK by P2SB
In the older platform such as Raptor Lake (RPL), Tiger Lake (TGL), it
needs PMC IPC cmd to turn on/off the corresponding clock.
Now on Meteor Lake (MTL), it control pcie clock registers on P2SB on
IOE or SoC die.
BUG=b:288976547, b:289461604
TEST=Test on google/screebo and found the pcie clock is on/off properly
and sdcard pcie port doesn't block S0ix with RTD3 cold enabled.
