Subject: [PATCH] ARM: dts: rockchip: rv11xx-evb-v10: add GT917S tp support

Gt917s is a panel adapter board with ili9881d matching touch IC.

At the same time, init delay Ms 80 instead of 10, is to solve the
problem of high probability of not displaying due to incomplete
reset when the hardware of the panel adapter board is changed.
