swiotlb: Remove bounce buffer remapping for Hyper-V
With changes to how Hyper-V guest VMs flip memory between private
(encrypted) and shared (decrypted), creating a second kernel virtual
mapping for shared memory is no longer necessary. Everything needed
for the transition to shared is handled by set_memory_decrypted().
As such, remove swiotlb_unencrypted_base and the associated
code.
