soc/intel: Update API name `pmc_send_bios_reset_pci_enum_done`
This patch updates PMC API name from `pmc_send_pci_enum_done` to `pmc_send_bios_reset_pci_enum_done` to inform PMC IPC about BIOS done is also set along with PMC enumeration being done. BUG=b:270942083 TEST=Able to build and boot google/rex.
