        src/sys/dev/imcsmb: imc.c imcsmb.c imcsmb_reg.h imcsmb_var.h

Log Message:
Import imcsmb driver from FreeBSD.  This driver allows access to the
SMBus controllers which are part of the integrated memory controllers
on certain modern Intel CPUs.  These SMBus are attached only to the
memory DIMMs, so we provide only a minimum amount of functionality.

Deliberately not included in GENERIC, as on some motherboards there
can be conflicting access between the driver and the motherboard.  The
motherboards generally will provide a mechanism to synchronize access,
but the methods are likely proprietary;  the driver provides a place
for inserting user-provided synchronization.
