Add mp2891 driver in hwmon and add dt-bindings for it.

v4 -> v5:
    1. remove useless code in mp2891_identify()
    2. add Rob's Acked-by

v3 -> v4:
    1. add mp2891 to Makefile, Kconfig and MAINTAINERS file

    5. add const attribute to mp2891_info variable
    6. add mp2891 in alpha order

v2 -> v3:
    1. change PSC_VOLTAGE_IN, PSC_CURRENT_IN, PSC_TEMPERATURE,
        and PSC_POWER format from linear to direct
    2. add limit register writtings.
    3. fix some coding style issues
    4. move mp2891 dt-bindings to trivial devices

V1 -> V2:
    1. add limit register readings
    2. add status register readings
    3. change PSC_CURRENT_OUT format from linear to direct
    4. add more detailed explanation for special processing
