regmap: Reorder 'struct regmap'

On a x86_64, with configured with allmodconfig, pahole states that the
regmap structure is:

	/* size: 1048, cachelines: 17, members: 78 */
	/* sum members: 1006, holes: 9, sum holes: 35 */
	/* padding: 7 */
	/* member types with holes: 2, total: 2 */
	/* last cacheline: 24 bytes */

So, when such a struct is allocated, 2048 bytes are allocated, with most of
this space being wasted.

Move a few bools so that the size is reduced to 1024.

After this change, pahole gives:

	/* size: 1024, cachelines: 16, members: 78 */
	/* sum members: 1006, holes: 6, sum holes: 18 */
	/* member types with holes: 2, total: 2 */
