[PATCH 06/10] input: touchscreen: edt-ft5x06: fix driver autoprobing

[Felipe Balbi <balbi@ti.com>]

i2c devices match against struct i2c_device_id
even for CONFIG_OF case, so adding a struct of_device_id
doesn't change anything. As a result, currently, edt-ft5x06
will not autoprobe if built as a module.

To fix the issue and still maintain backwards compatibility
with all DTS files currently in tree, we're just moving
all ids from of_device_id to i2c_device_id while also
adding the following specific ids which should be used
from now on:

	{ "edt-ft5206", 0, }
	{ "edt-ft5306", 0, }
	{ "edt-ft5406", 0, }
