Add bindings for Ilitek. The ili9882t touch screen chip same as Elan eKTH6915 controller has a reset gpio. The difference is that ilitek9882 needs to use vccio-supply instead of vcc33-supply. From Dmitry suggestion, it would make more sense to distinguish the binging of ili9882 and eKTH6915.
From The datasheet specifies there should be 60ms between touch SDA sleep and panel RESX. so we can add the 65 ms delay in i2c_hid_core_suspend.
As Doug said, only the panel follower patch series[1] land makes sense, and now the panel follower patch series[1] has land. [1]: https://lore.kernel.org/all/20230727171750.633410-1-dianders@chromium.org
