[PATCH] drm/panel: novatek-nt37801: Use mipi_dsi_*_multi() functions

["Nicolás Antinori" <nico.antinori.7@gmail.com>]

Replace mipi_dsi_* functions with their non-deprecated mipi_dsi_*_multi
counterparts. This change reduces error-checking boilerplate and improves
readability.

Note: I Compile-tested this patch since I don't own the panel to test it.
