Tom Lendacky 072f58c6ce x86/mm: Use encrypted access of boot related data with SEV 
When Secure Encrypted Virtualization (SEV) is active, boot data (such as
EFI related data, setup data) is encrypted and needs to be accessed as
such when mapped. Update the architecture override in early_memremap to
keep the encryption attribute when mapping this data.
