The regmap functions currently assume that all register map accesses have a data width of 32 bits, but there are maps that have different widths.
To rectify this, implement the regmap_raw_read and regmap_raw_write functions from the Linux kernel API that specify the width of a desired read or write operation on a regmap.
Implement the regmap_read and regmap_write functions using these raw functions in a backwards-compatible manner.

v3 -> v4:
- Switched 'ranges[0] + offset' to 'ranges[0].start + offset'
- Explained the difference between the raw and non-raw read/write functions better in the docs
v2 -> v3:
- Implement the "raw" functions from Linux instead of adding a size parameter to the regmap_{read,write} functions
- Fixed style violation
- Improved error handling
v1 -> v2: New in v2
