The newly added driver calls functions for accessing the DT but
does not include the header they are defined in, which fails
in configurations in which we don't get the header implicitly
through something else:

drivers/input/touchscreen/colibri-vf50-ts.c: In function 'vf50_ts_probe':
drivers/input/touchscreen/colibri-vf50-ts.c:302:10: error: implicit declaration of function 'of_property_read_u32' [-Werror=implicit-function-declaration]

This adds an explict #include, to ensure we can always build it.
