static const size_t kMaxMsiVectors

uint8_t MmcToCount (uint16_t reg_value)

These methods convert from the mm_capable register values to irq count and

back. The register stores the nth power of two rather than the count itself

to save bits, but it's easier to lean on the compiler here than use pow()

methods. PCI Local Bus Specification v3.0 section 6.8.1.3.
