[PATCH v12 5/5] Input: goodix - add support for gt9157

[Irina Tirdea <irina.tirdea@intel.com>]

Goodix touchscreen GT9157 has the same basic functionality
as GT911 touchscreen. This is based on Goodix datasheets
for GT911 and GT9157 and on Goodix driver gt9xx.c for
Android (publicly available in Android kernel trees for
various devices).
