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 <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202311151746.f7u7dzbZ-lkp@intel.com/
Signed-off-by: Liu Ying <victor.liu@nxp.com>

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