[PATCH 07/13] drm_print: condense enum drm_debug_category

[Jim Cromie]

enum drm_debug_category has 10 "classes", explicitly initialized with
0x-bitmasks which could be simplified as BIT(X)s.  But lets go
further: use natural enumeration (int, starting at 0), and do the
BIT(cat) in drm_debug_enabled(cat) at runtime.

While this slightly pessimizes the bit-test, the category now fits in
4 bits, allowing it in struct _ddebug.class_id:4.  This sets us up to
adapt drm to use dyndbg with JUMP_LABEL, thus avoiding all those
bit-tests anyway.
