Add hooks to regulator_get_current_limit_regmap() and regulator_set_current_limit_regmap() with an accompanying map of amperages. This lets us use the existing helper functions to map requested current settings to register bit-map/indicies. This change is required to elevate the default 2 Amps set by the bootloader to 3 Amps or indeed to constrain the value lower as the system design may dictate. The valid range is 500 mA to 3 A in increments of 500 mA.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
