drivers/input: Add driver for Goodix GT9XX Touch Panel
This PR adds the driver for Goodix GT9XX I2C Touch Panel, which will be called by PINE64 PinePhone.
Our driver follows the design of the NuttX Driver for [Cypress MBR3108](https://github.com/apache/nuttx/blob/master/drivers/input/cypress_mbr3108.c).
We have documented our driver here: ["NuttX Touch Panel Driver for PinePhone"](https://lupyuen.github.io/articles/touch2#appendix-nuttx-touch-panel-driver-for-pinephone)
`drivers/input/Kconfig`: Added option `INPUT_GT9XX` to select GT9XX Driver
`drivers/input/Make.defs`: Added GT9XX Driver to Makefile
`drivers/input/gt9xx.c`, `gt9xx.h`: I2C Driver for GT9XX Touch Panel
