The regmap binding talks about one thing, which is register
endianess, and it gets almost every aspect of it wrong.
This replaces the current text of the file with a version
that makes more sense and that matches what we implement
now.

Currently the binding document says that if no endianness is configured
we use native endian but this is not in fact true for all binding types
and we do have some devices that really want native endianness such as
Broadcom MIPS SoCs where switching the endianness of the CPU also
switches the endianness of external IPs.
Provide an explicit option for this.

Device-Tree binding for device endianness
Index Device Endianness properties
---------------------------------------------------
1 BE 'big-endian'
2 LE 'little-endian'
For one device driver, which will run in different scenarios above
on different SoCs using the devicetree, we need one way to simplify
this.
