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.

Switch to using gpiod_set_value_cansleep() when controlling reset_gpio to
support GPIO providers that may sleep, such as I2C GPIO expanders.

Further switch the mdelay calls on the reset path to fsleep (preferred
in non-atomic contexts).

This fixes noisy complaints in kernel log for gpio providers that do
sleep.
