Dynamically update touchscreen power enable GPIO in devicetree.<br>b. Provide default and bid0 tables for GPIO configuration in ramstage.<br>c. Configure WLAN enable GPIO differently in bootblock based on<br>boardid.<br>d. Disable unused I2C devices in devicetree.<br><br>BUG=b:112458032<br>TEST=No errors observed on boot-up on fleex.<br><br>Change-Id: Ib4c449168b08e2393e2395d6b49469be5599c2ce<br>Signed-off-by: Furquan
