[RFC PATCH v1 08/19] target/i386: rename hvf_mmio_buf to mmio_buf

[Wei Liu <liuwe@linux.microsoft.com>]

We want to refactor HVF's instruction emulator to a common component. Renaming
hvf_mmio_buf removes the association between HVF and the instruction emulator.

The definition of the field is still guarded by CONFIG_HVF for now, since it is
the only user.

No functional change.
