soc/intel/alderlake: Refactor SoC code to maintain CPU and PCH PCIE RPs
List of changes: 1. Create new Kconfig MAX_CPU_ROOT_PORTS and MAX_PCH_ROOT_PORTS as per EDS. 2. Add new chip variable to enable/disable CPU PCIE RPs from mainboards. 3. Rename PcieRpEnable to PchPcieRpEnable. 4. Enable CPU RPs as below in mainboard devicetree.cb RP1: PEG60 : 0:6:0 : CPU SSD1 RP2: PEG10 : 0:1:0 : x8 CPU Slot RP3: PEG62 : 0:6:2 : CPU SSD2 Change-Id: I92123450bd7cfb2e70aae8de03053672a7772451 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/49136 Reviewed-by: EricR Lai <ericr_lai@compal.corp-partner.google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
