This series adds support for the Goodix Berlin-A series touch ICs
(gt9897). This was tested on a Xiaomi 11 Lite 5G NE (xiaomi-lisa),
which uses the gt9897 IC connected over SPI. I am not aware of any
device that has gt9897 connected over I2C and therefore could not
test it, so I didn't add a compatible in the I2C driver.

Changes in v3:
- Store the ic data in the goodix_berlin_core struct and pass it to
  goodix_berlin_probe from the i2c/spi probes (requested by Neil)
- Resent from my now preferred e-mail for kernel work

Changes in v2:
- Added Rob's A-b tag (patch no. 1)
- Added Luca's T-b tag (patch no. 2)
- Updated the i2c and spi device id tables with the driver data and
  switched to spi_get_device_match_data where possible (requested by
  Neil)
- Switched to device_get_match_data in goodix_berlin_core.c
- Move all revision specific addresses and other properties into the
  goodix_berlin_ic_data struct (requested by Dmitry)
- Link to v1:
