Subject: [PATCHv2 2/3] x86/sev: Rename mem_encrypt.c to mem_encrypt_amd.c

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>

Both TDX and AMD SEV/SME implement memory encryption features. But
the bulk of the code in mem_encrypt.c is AMD specific. Rename the
file to mem_encrypt_amd.c. A subsequent patch will extract the
parts that can be shared by both TDX and AMD SEV/SME into a generic
file.

No functional changes.
