msm: mhi: MHI Usperspace Control Interface driver



The MHI UCI driver exposes MHI core functionality to
userspace by means of device nodes.

The UCI driver exposes a device node for a pair of unidirectional
MHI channels.

The supported system calls on the device nodes are read, write,
select/poll and RS232 IOCTLs.
