This is an RFC to get input on how people feel about moving towards
using <linux/bits.h> and <linux/bitfield.h> macros for register field
definitions and manipulation:
* BIT()
* GENMASK()
BIT/GENMASK macros assumes 'unsigned long' type (64b) while our registers
(and some of our temporary variables) are 'unsigned int' (32b).
It was reported [1] that use of plain BIT(0) may cause compilation issues.
