Fei Shao b5f4d19150 dt-bindings: input: goodix: Add "goodix,no-reset-during-suspend" property
[ Upstream commit 359ed24a0d ]

We observed that on Chromebook device Steelix, if Goodix GT7375P
touchscreen is powered in suspend (because, for example, it connects to
an always-on regulator) and with the reset GPIO asserted, it will
introduce about 14mW power leakage.

To address that, we add this property to skip reset during suspend.
If it's set, the driver will stop asserting the reset GPIO during
power-down. Refer to the comments in the driver for details.
