Tom Lendacky 38eecccdf4 x86/efi: Update EFI pagetable creation to work with SME 
When SME is active, pagetable entries created for EFI need to have the
encryption mask set as necessary.

When the new pagetable pages are allocated they are mapped encrypted. So,
update the efi_pgt value that will be used in CR3 to include the encryption
mask so that the PGD table can be read successfully. The pagetable mapping
as well as the kernel are also added to the pagetable mapping as encrypted.
All other EFI mappings are mapped decrypted (tables, etc.).
