Subject: [PATCH 17/49] regmap-irq: Add broken_mask_unmask flag

This flag is necessary to prepare for fixing the behavior of unmask
registers. Existing chips that set mask_base and unmask_base must
set broken_mask_unmask=1 to declare that they expect the mask bits
will be inverted in both registers, contrary to the usual behavior
of mask registers.
