Before adding the support for ADPM12160, this series includes a commit
to fix the issue with max34451. The family of max344** contains switched
PMBUS addresses 0x46 and 0x4A. For max34451, the version MAX34451ETNA6+
and later fixed this issue and this first commit supports this. The
MFR_REVISION is used to differentiate the different max34451 chips.

The second commit adds the actual driver for adpm12160. ASPM12160 is a
quarter brick DC/DC Power Module. It is a high power non-isolated
converter capable of delivering a fully regulated 12V, with continuous
power level of 1600W with peak power at 2400W for a limited time.
Uses PMBus Configuration.
