[PATCH] regmap: regmap-irq: Make irq-type callbak optional

[Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>]

Do not register type setting callback if HW does not support
setting the irq type. IRQ core can then handle cases where
type setting is not supported and no regmap-irq specific handling
is required.
