Add a new Kconfig for the accel subsystem. The Kconfig currently contains only the basic CONFIG_DRM_ACCEL option that will be used to decide whether to compile the accel registration code. Therefore, the kconfig option is defined as bool. The accel code will be compiled as part of drm.ko and will be called directly from the DRM core code. The reason we compile it as part of drm.ko and not as a separate module is because of cyclic dependency between drm.ko and the separate module (if it would have existed). This is due to the fact that DRM core code calls accel functions and vice-versa. The accelerator devices will be exposed to the user space with a new, dedicated major number - 261. The accel init function registers the new major number as a char device and create corresponding sysfs and debugfs root entries, similar to what is done in DRM init function. I added a new header called drm_accel.h to include/drm/, that will hold the prototypes of the drm_accel.c functions. In case CONFIG_DRM_ACCEL is set to 'N', that header will contain empty inline implementations of those functions, to allow DRM core code to compile successfully without dependency on CONFIG_DRM_ACCEL. I Updated the MAINTAINERS file accordingly with the newly added folder and I have taken the liberty to appropriate the dri-devel mailing list and the dri-devel IRC channel for the accel subsystem.
