Input: goodix-berlin - add SPI support for Goodix Berlin Touchscreen IC
Add initial support for the new Goodix "Berlin" touchscreen ICs
over the SPI interface.
The driver doesn't use the regmap_spi code since the SPI messages
needs to be prefixed, thus this custom regmap code.
This initial driver is derived from the Goodix goodix_ts_berlin
available at [1] and [2] and only supports the GT9916 IC
present on the Qualcomm SM8550 MTP & QRD touch panel.
The current implementation only supports BerlinD, aka GT9916.
