Subject: [PATCH] input: touchscreen: edt-ft5x06: select REGMAP_I2C

After starting to use regmap API to access registers the edt-ft5x06
driver depends on symbols provided by REGMAP_I2C:

edt-ft5x06.o: in function `edt_ft5x06_ts_probe':
edt-ft5x06.c:1154: undefined reference to `__regmap_init_i2c'
edt-ft5x06.o: in function `edt_ft5x06_ts_identify':
edt-ft5x06.c:897: undefined reference to `__regmap_init_i2c'

Make sure support for I2C regmap is actually selected by adding this
dependency to Kconfig.
