drm/mipi-dsi: use correct return type for the DSC functions
[ Upstream commit de1c705c50326acaceaf1f02bc5bf6f267c572bd ]
The functions mipi_dsi_compression_mode() and
mipi_dsi_picture_parameter_set() return 0-or-error rather than a buffer
size. Follow example of other similar MIPI DSI functions and use int
return type instead of size_t.
