boards: nxp: rd_rw612_bga: add support for goworld 16880 display module

Add support for the goworld 16880 display module. As this display module
only features an FFC cable, it is added as a board overlay for the RW612
BGA. This module uses an ST7796S display controller as well as an FT7401
touch controller (which is managed by the FT5336 input driver)
