staging: vchiq: Add details to Kconfig help texts 



Add some details to the Kconfig definitions of $CONFIG_VCHIQ_CDEV and
$CONFIG_BCM2835_VCHIQ to help make the motive behind the configs a bit
more clear.

		Kernel to VideoCore communication interface for the

		BCM2835 family of products.

		Defaults to Y when the Broadcom Videocore services

		are included in the build, N otherwise.

		Broadcom BCM2835 and similar SoCs have a VPU called VideoCore. This config

		enables the VCHIQ driver, which implements a messaging interface between

		the kernel and the firmware running on VideoCore. Other drivers use this

		interface to communicate to the VPU. More specifically, the VCHIQ driver is

		used by audio/video and camera drivers as well as for implementing MMAL

		API, which is in turn used by several multimedia services on the BCM2835

		family of SoCs.

		Defaults to Y when the Broadcom Videocore services are included in

		the build, N otherwise.

	help

		Enable the creation of VCHIQ character driver to help

		communicate with the Videocore platform.

		Enable the creation of VCHIQ character driver. The cdev exposes ioctls used

		by userspace libraries and testing tools to interact with VideoCore, via

		the VCHIQ core driver (Check BCM2835_VCHIQ for more info).

		This can be set to 'N' if the VideoCore communication is not needed by

		userspace but only by other kernel modules (like bcm2835-audio).  If not

		sure, set this to 'Y'.
