Old sequence:
1. Pull the MIPI signal high
2. Delay & Dsi_reset
3. Set the dsi timing register
4. dsi clk & lanes leave ulp mode and enter hs mode

The sequence after patching is:
1. Set the dsi timing register
2. Pull the MIPI signal high
3. Delay & Dsi_reset
4. dsi clk & lanes leave ulp mode and enter hs mode
