MLK-12948 ARM: dts: imx7d-sdb: change the hardware reset gpio for mipi dsirel_imx_4.1.15_1.2.0_ga
Change the hardware reset gpio to 'GPIO6_IO15' for mipi dsi to
allow fec2 and mipi dsi can run at the same time. This needs
some hardware rework as follows:
"
1. Replace R631 with 100K resistor;
2. Remove D14, D24;
3. Solder the Cathode of the diode to R471,
you can use BAT54HT1(ONSEMI) or NSR0320MW2T1G(ONSEMI);
4. Solder the wire to the Anode end of the diode;
5. Scrape the solder mask(Green oil) of the MIPI Reset via,
then solder the end of the wire to the via.
