kernel/modules/other/mlxreg: add new package

Browse Source 
This commit adds a new mlxreg package, which allows access
to Mellanox programmable device register space through sysfs
interface for thermal control and hardware management.

It also adds required Mellanox I²C drivers and packages
for the "special" MSN4800 series and SN2201 platform.
