[PATCH v1 1/2] drm/print: describe 6th & 9th bit of drm.debug

[Michał Grzelak <michal.grzelak@intel.com>]

Setting 6th or 9th bit of drm.debug change debug logging. Meanwhile
`modinfo drm` does not inform about it at all.

Add info to MODULE_PARAM_DESC(debug, ...) about setting 6th and 9th bit
basing on DECLARE_DYNDBG_CLASSMAP(drm_debug_classes, ...). Match
description of corresponding bits with enum drm_debug_category. Include
9th bit in the example with enabling all possible logging provided at
comment at include/drm/drm_print.h.
