Merge branch 'regmap-simple-bit-helpers'

====================
regmap: provide simple bitops and use them in a driver

I noticed that oftentimes I use regmap_update_bits() for simple bit
setting or clearing. In this case the fourth argument is superfluous as
it's always 0 or equal to the mask argument.

This series proposes to add simple bit operations for setting, clearing
and testing specific bits with regmap.

The second patch uses all three in a driver that got recently picked into
the net-next tree.

The patches obviously target different trees so - if you're ok with
the change itself - I propose you pick the first one into your regmap
tree for v5.8 and then I'll resend the second patch to add the first
user for these macros for v5.9.

v1 -> v2:
- convert the new macros to static inline functions

v2 -> v3:
- drop unneeded ternary operator
