Pull power sequencing updates from Bartosz Golaszewski:
 "For this release we have an extension of the pwrseq-pcie-m2 driver
  with support for PCIe M.2 Key E connectors.

  The rest of the commits fulfill a supporting role: document the
  hardware in DT bindings, provide required serdev helpers (this has
  been provided in an immutable branch to Rob Herring so you may see it
  in his PR as well) and is followed up by some Kconfig fixes from Arnd.

  Summary:

   - add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2

   - describe PCIe M.2 Mechanical Key E connectors in DT bindings

   - add serdev helpers for looking up devices by OF nodes

   - minor serdev core rework to enable support for PCIe M.2 Key E
     connectors"
