OvmfPkg/Bhyve: use a proper PCI IO range
Bhyve uses an io port range of [ 0x2000, 0x10000 ] [1]. At the moment,
EDKII is using a subset of this range [ 0xC000, 0x10000 ] [2]. Even
though the EDKII range doesn't exceed the bhyve range, it's causing
issues on some guests like OpenBSD [3]. We don't know why it's causing
issues yet. However, using the same IO port range in EDKII fixes the
issue and is a good idea anyway.
