x86/sev: Move sev_setup_arch() to mem_encrypt.c

Browse source

Since commit:

  4d96f91091 ("x86/sev: Replace occurrences of sev_active() with cc_platform_has()")

... the SWIOTLB bounce buffer size adjustment and restricted virtio memory
setting also inadvertently apply to TDX: the code is using
cc_platform_has(CC_ATTR_GUEST_MEM_ENCRYPT) as a gatekeeping condition,
which is also true for TDX, and this is also what we want.

To reflect this, move the corresponding code to generic mem_encrypt.c.

No functional changes intended.
