[PATCH 04/15] ASoC: SDCA: Pass device register map from IRQ alloc to handlers

[Charles Keepax <ckeepax@opensource.cirrus.com>]

Store a copy of the device register map in the structure for the IRQ
handlers. This will allow the individual IRQ handlers access to the
device level register map if required.
