Tom Lendacky 2b5d00b6c2 x86/mm: Centralize PMD flags in sme_encrypt_kernel() 
In preparation for encrypting more than just the kernel during early
boot processing, centralize the use of the PMD flag settings based
on the type of mapping desired.  When 4KB aligned encryption is added,
this will allow either PTE flags or large page PMD flags to be used
without requiring the caller to adjust.
