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
