msix: Add simple BAR allocation MSIX setup functions
msi_init() takes over a BAR without really specifying or allowing
specification of how it does so. Instead, let's split it into
two interfaces, one fully specified, and one trivially easy. This
implements the latter. msix_init_exclusive_bar() takes over
allocating and filling a PCI BAR _exclusively_ for the use of MSIX.
When used, the matching msi_uninit_exclusive_bar() should be used
to tear it down.
