mb/google/brya: Support power sequencing for USB-only WWAN

Nissa is using the FM101 which is USB only. To allow us to reuse the
existing wwan_power.asl for power sequencing, move the PCIe-specific
part behind a new Kconfig HAVE_PCIE_WWAN.

BUG=b:217092522
TEST=Build brya0 and check that generated dsdt.asl doesn't change.
