[PATCH 10/10] firmware: cs_dsp: Allow creation of event controls

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

Some firmwares contain controls intended to convey firmware state back
to the host. Whilst more infrastructure will probably be needed for
these in time, as a first step allow creation of the controls, so said
firmwares arn't completely rejected.
