  efi: clean up Kconfig dependencies on CONFIG_EFI (2022-06-01 14:08:13 +0200)

----------------------------------------------------------------
Follow-up tweaks for the EFI changes in v5.19

- fix new DXE service invocations for mixed mode
- use correct Kconfig symbol when setting PE header flag
- clean up the drivers/firmware/efi Kconfig dependencies so that
  features that depend on CONFIG_EFI are hidden from the UI when the
  symbol is not enabled.

Also included is a RISC-V bugfix from Heinrich to avoid read-write
mappings of read-only firmware regions in the EFI page tables.
