[PATCH] ARM: dts: sun7i: Add Goodix GT911 nodes for Wexler TAB7200

[mamlinav@gmail.com (Aleksei Mamlin)]

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:
https://git.kernel.org/cgit/linux/kernel/git/dtor/input.git/commit/?h=next&id=771d8f1b178e7e09fcc641fccd48852958dbc329

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