[PATCH v2] drm/bridge: imx93-mipi-dsi: Fix a couple of building warnings

[Liu Ying]

Fix a couple of building warnings on used uninitialized 'best_m' and
'best_n' local variables by initializing 'best_m' to zero and 'best_n'
to UINT_MAX.  This makes compiler happy only.  No functional change.

Fixes: ce62f8ea7e3f ("drm/bridge: imx: Add i.MX93 MIPI DSI support")
Reported-by: kernel test robot 
Closes:

v2:
* Initialize 'best_n' to UINT_MAX instead of zero. (Maxime)
