input: it7258_ts_i2c: add low reset and reset delay support
Add low reset gpio and delay reset support for ITE tech
driver.
ITE tech controller support low reset gpio configuration. This
property is parsed from the DT, and reset gpio is set to low.
Reset delay value is also parsed from DT which is required by the
ITE tech controller.
