Add support of external MIPI DSI display in VIM3 Android 9

VIM3
43

Hello, here I use the TS101 MIPI screen on VIM3 as an example:

pixel_clk:
It needs to be configured according to actual needs. Calculation method of pixel_clk: pixel_clk = h_period * v_period *
frame_rate. pixel_clk can also directly set the frame rate value. frame_rate is generally 60HZ

bit_rate_max:
Please check the specification book to determine this value. If it is not provided, you need to follow the formula pclk * 3 * 8 = bit_rate *
lane_num (both 6bit and 8bit lcd are calculated according to 8bit)

The relevant h_period and h_period examples below have comments that you can use as a reference.

lcd_2{
			model_name = "TS101";
			interface = "mipi";
			basic_setting = <1920 1200 /*h_active, v_active*/
				2066 1229 /*h_period, v_period*/
				8 /*lcd_bits*/
				154 86>; /*screen_widht, screen_height*/
			lcd_timing = <4 23 0 /*hs_width, hs_bp, hs_pol*/
				4 14 0>; /*vs_width, vs_bp, vs_pol*/
			clk_attr = <0xff /*fr_adj_type(0=clk, 1=htotal, 2=vtotal)*/
				0 /*clk_ss_level */
				1 /*clk_auto_generate*/
				152346840>; /*pixel_clk(unit in Hz)*/
			mipi_attr = <4 /*lane_num*/
				1000 /*bit_rate_max(MHz)*/
				0 /*factor(*100, default 0 for auto)*/
				1 /*operation_mode_init(0=video, 1=command)*/
