regmap: Reorder fields in 'struct regmap_bus' to save some memory
Group some bool variables to reduce hole and avoid padding.
On x86_64, this shrinks the size from 136 to 128 bytes.
As an example:
$ size drivers/base/regmap/regmap-fsi.o (Before)
text data bss dec hex filename
4837 136 0 4973 136d drivers/base/regmap/regmap-fsi.o
$ size drivers/base/regmap/regmap-fsi.o (After)
text data bss dec hex filename
4701 136 0 4837 12e5 drivers/base/regmap/regmap-fsi.o
