Add support for MP2971 and MP2973, the successor of MP2975.
The major differences are:
- On MP2973 and MP2971 the Vref cannot be read and thus most of
the OVP/current calculations won't work.
- MP2973 and MP2971 also support LINEAR format for VOUT
- MP2973 and MP2971 do not support OVP2
- On MP2973 and MP2971 most registers are in LINEAR format
- The IMVP9_EN bit has a different position
- Per phase current sense haven't been implemented.
As on MP2975 most of the FAULT_LIMIT and WARN_LIMIT registers
have been redefined and doesn't provide the functionality as
defined in PMBUS spec.
Tested on MP2973 and MP2971.
