[PATCH 03/10] Input: ilitek_ts_i2c: fix warning with gpio controllers that sleep

The ilitek touchscreen driver uses the non-sleeping gpiod_set_value
function for reset.

When the connected gpio controller needs to sleep as is common for i2c
based expanders, this causes noisy complaints in kernel log.

Reset is not time-critical, switch to the gpiod_set_value_cansleep
variant.
