soc/intel/meteorlake: Move P2SB PCI resource into P2SB device
This patch ensures the P2SB PCI device resource is getting reserved
so that the resource allocator is not assigning this resource to any
other PCI device during the PCI enumeration.
BUG=b:254207628
TEST=Able to ensure on the Google/Rex device, the PCI enumeration
is not assigning the P2SB BAR (0xE000_0000) to TBT Root Port3.
Instead the 0xE000_0000 address is being assigned to the P2SB
PCI device.
Without this patch:
