power: sequencing: pcie-m2: enforce PCI and OF dependencies

The driver fails to build when PCI is disabled:

drivers/power/sequencing/pwrseq-pcie-m2.c: In function 'pwrseq_pcie_m2_register_notifier':
drivers/power/sequencing/pwrseq-pcie-m2.c:368:54: error: 'pci_bus_type' undeclared (first use in this function); did you mean 'pci_pcie_type'?
  368 |                         ret = bus_register_notifier(&pci_bus_type, &ctx->nb);
      |                                                      ^~~~~~~~~~~~
      |                                                      pci_pcie_type

Similarly, when CONFIG_OF is disabled:

drivers/power/sequencing/pwrseq-pcie-m2.c: In function 'pwrseq_m2_pcie_create_bt_node':
drivers/power/sequencing/pwrseq-pcie-m2.c:191:9: error: implicit declaration of function 'of_changeset_init' [-Wimplicit-function-declaration]
  191 |         of_changeset_init(ctx->ocs);
      |         ^~~~~~~~~~~~~~~~~

Make both dependencies unconditional to prevent compile-testing
in either configuration.
