[PATCH v10 4/5] staging: bcm2835-audio: Register bcm2835-audio with vchiq_bus_type

[Umang Jain <umang.jain@ideasonboard.com>]

Similar to how bcm2385-camera device is registered, register the
bcm2835-audio with vchiq_bus_type as well.

Meanwhile at it, change the name and module alias from "bcm2835_audio"
to "bcm2835-audio" to be consistent with bcm2835-camera device. This
does not brings any functional change as '-' and '_' are
interchangeable as per modprobe man pages.
