soc/intel/alderlake: Determine PCIe RP enable mask using device on/off status

This change uses the newly added helper function
`pcie_rp_enable_mask()` to determine the mask of PCH and CPU PCIe root
ports that are enabled by the mainboard instead of relying on
PcieRpEnable[] config.

Since pch_lp_rp_groups are used by more than just chip.c, this change
also adds pcie_rp.c that provides a helper function to get the PCIe RP
group table for the PCH.
