[RFC PATCH 1/3] drivers/accel: add new kconfig and update MAINTAINERS

Add a new Kconfig for the accel subsystem. The Kconfig currently
contains only the basic CONFIG_ACCEL option that will be used to
decide whether to compile the accel registration code as part of the
drm core functionality.

I have taken the liberty to appropriate the dri-devel mailing list and
the dri-devel IRC channel for the accel subsystem.

+	  Framework for device drivers of compute acceleration devices, such
+	  as, but not limited to, Machine-Learning and Deep-Learning
+	  acceleration devices.
+	  If you say Y here, you need to select the module that's right for
+	  your acceleration device from the list below.
+	  This framework is integrated with the DRM subsystem as compute
+	  accelerators and GPUs share a lot in common and can use almost the
+	  same infrastructure code.
+	  Having said that, acceleration devices will have a different
+	  major number than GPUs, and will be exposed to user-space using
+	  different device files, called accel/accel* (in /dev, sysfs
+	  and debugfs)
