drm/panel/synaptics-r63353: Use _multi variantsHEADdrm-misc-next

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 _multi variant APIs,
replacing mpi_dsi_msleep() where necessary and for returning
dsi_ctx.accum_err in these functions. Manually handled the
reset step before returning from r63353_panel_activate()

v2: Do not skip the reset in case of error during
panel activate (Dmitry)
- Convert all usleep_range()

v3: mipi_dsi_usleep_range() is to be used only when in
between _multi commands(Doug)
- Check for error once in the end while using _multi
variants (Doug)

v4: Change return type of r63353_panel_deactivate() to void (Doug)
