[PATCH v2 04/14] target/i386: rename hvf_mmio_buf to emu_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.

v2: mmio_buf -> emu_mmio_buf per suggestion from Paolo
