Add an IOCTL to send mailbox commands to PUNIT using PUNIT PCI device. A limited set of mailbox commands can be sent to PUNIT. This MMIO interface is used by the intel-speed-select tool under tools/x86/power to enumerate and control Intel Speed Select features. The MBOX commands ids and semantics of the message can be checked from the source code of the tool.
