This patch adds nodes for the Goodix GT911 touchscreen controller found
on the Wexler TAB7200 tablet. Controller uses one of following I2C
addresses: 0x5d or 0x14, so just add two nodes.

DT support for the Goodix GT911 touchscreen controller has been queued up
by Dmitry Torokhov for merging into 4.1:

IRQ flags are set by the touchscreen controller driver, so use IRQ_TYPE_NONE.
