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. " Signed-off-by: Fancy Fang <chen.fang@nxp.com> (cherry picked from commit 0af28564e73f006f742a9af0db4bc5b8588e3490)
