The CR3 register entry can contain the SME encryption mask that indicates
the PGD is encrypted. The encryption mask should not be used when
creating a virtual address from the CR3 register, so remove the SME
encryption mask in the read_cr3_pa() function.
During early boot SME will need to use a native version of read_cr3_pa(),
so create native_read_cr3_pa().
