drm/bridge: imx93-mipi-dsi: Fix a couple of building warnings

[ Upstream commit 325b71e820b67569048c621227266783442b75ed ]

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.
