regmap: provide regmap_field helpers for simple bit operations

Browse Source 
We have set/clear/test operations for regmap, but not for regmap_field yet.
So let's introduce regmap_field helpers too.

In many instances regmap_field_update_bits() is used for simple bit setting
and clearing. In these cases the last argument is redundant and we can
hide it with a static inline function.

This adds three new helpers for simple bit operations: set_bits,
clear_bits and test_bits (the last one defined as a regular function).
