Allow a 4-byte write to PCI config space to overlap
the 2 read-only bytes at the start of a PCI capability. This is the sequence that OpenBSD uses when enabling MSI interrupts, and works fine on real h/w. In bhyve, convert the 4 byte write to a 2-byte write to the r/w area past the first 2 r/o bytes of a capability. Reviewed by: neel Approved by: re@ (blanket)
