drivers/ft5x06: configure interrupt mode in any case

gschorcht · gschorcht · commit bf720c0b41ef · 2023-08-28T18:50:04.000+02:00
The interrupt mode has to be configured independent on whether the INT pin is initialized already by the `ft5x06_init` function if parameter `cb` is defined or later, for example by the `touch_dev` implementation.
