Remove driver-specific regmap wrappers in favor of using regmap helpers
directly. The wrappers are mostly equivalent to the standard helpers, with
two exceptions: regmap_read requires an unsigned int pointer, and
regmap_update_bits has the mask and value arguments swapped. These
differences were accounted for and adjusted accordingly.

We refer to functions as func(), exempli gratia, regmap_read().

While at it, move towards reversed xmas tree order

It's better to replace this to use _set_bits()/_clear_bits() or even move from
the above conditional (not in this context) to _assign_bits().

Ditto.

_clear_bits().

 	if (ret) {

 		return ret;

_set_bits()

 	if (ret)

_assign_bits() and so on...

We don't need to keep 'extern' for ages.
