ARM: dts: rockchip: fix timing configs of panel k350c4516t for rv1103/rv1106 evb

Browse Source 
1. Modify mcu-timing configs according to panel datasheet.
2. Modify clock-frequency config sync with mcu-timing
   configs.
3. Add more comments for panel initialization sequence.
4. Add 10ms delay before sending initialization sequence
   to make sure the reset gpio output a low pulse.
5. Remove unused parameter reset-value.
