drm/msm/dp: fix the max supported bpp logic
Fix the dp_panel_get_supported_bpp() API to return the minimum
supported bpp correctly for relevant cases and use this API
to correct the behavior of DP driver which hard-codes the max supported
bpp to 30.
This is incorrect because the number of lanes and max data rate
supported by the lanes need to be taken into account.
Replace the hardcoded limit with the appropriate math which accounts
for the accurate number of lanes and max data rate.
changes in v2:
- Fix the dp_panel_get_supported_bpp() and use it
- Drop the max_t usage as dp_panel_get_supported_bpp() already
returns the min_bpp correctly now
changes in v3:
- replace min_t with just min as all params are u32
