Subject: [PATCH] drm/panel/synaptics-r63353: Use _multi variants
Move away from using deprecated API and use _multi
variants if available. Use mipi_dsi_msleep()
and mipi_dsi_usleep_range() instead of msleep()
and usleep_range() respectively.
Used Coccinelle to find the multiple occurences.

Previous attempt for this change was addressed in:[1]
The series did not handle returns properly and still
used msleep() and usleep_range() API.
It also collided with an Tejas's similar efforts.
Will be sending the patches per driver instead of
major haul of changes.
Following [2] for reference.
