    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
