EFI fixes for v5.10-rc5

Please pull the changes below. The efivarfs patch fixes a regression that was introduced by a 'bug fix' last week, but this turned out to result in double frees that trigger BUG()s when CONFIG_SLAB_FREELIST_HARDENED is enabled.

The following changes since commit c2fe61d8be491ff8188edaf22e838f819999146b:

efi/x86: Free efi_pgd with free_pages() (2020-11-10 19:18:11 +0100)

efi: EFI_EARLYCON should depend on EFI (2020-11-25 16:55:02 +0100)

----------------------------------------------------------------
More EFI fixes for v5.10-rc:
- revert efivarfs kmemleak fix again - it was a false positive;
- make CONFIG_EFI_EARLYCON depend on CONFIG_EFI explicitly so it does not pull in other dependencies unnecessarily if CONFIG_EFI is not set
- defer attempts to load SSDT overrides from EFI vars until after the efivar layer is up.
