disp: msm: dsi: add indexing for panel timing nodes

Browse Source 
The order of the panel timing nodes specified in the device tree is
not guaranteed to be the same while being parsed in the driver. This
results in unintended modes being set as preferred timing mode. The change
introduces cell-index property, so that the timing modes can be
accurately indexed and parsed.
