That's certainly a dsi host issue (to slow AHB/APB host clock?). With a 
Synopsis DSI host it takes < 10 ms when called in .enable.

Why did you remove that and instead of just make 
mipi_dsi_dcs_write_buffer to mipi_dsi_dcs_write_seq_multi and call it in 
.prepare if you think that improves anything? The code looks rather ugly 
now, imho.
