[PATCH 11/22] drm/amd/display: refine code for dmcub inbox1 ring buffer debug

[Tom Chung]

From: Fudongwang <fudong.wang at amd.com>

[Why]
1. To watch dmcub inbox1 ring buffer cmd type without tools
2. dmub_cmd_PLAT_54186_wa 66 bytes

[How]
Added dmcub cmd type enum: unsigned char for debug use only,
also fixed 66 bytes issue by using unsigned int in bit
define instead of unsigned char.
