boards: shields: lcd_par_s035: enable reset gpio within input module

The LCD_PAR_S035 display module shares the reset pin between the display
module and the touchscreen controller. The touchscreen controller needs
the reset pin to be toggled low during boot in order to select the
expected I2C address. However, the reset sequence must occur before the
display is initialized. To enable this, set a custom INPUT driver init
priority when using this display module, so that INPUT drivers start
after MIPI DBI drivers but before DISPLAY drivers.

Since the reset sequence is now operating as expected, we no longer need
to use the alt-addr probing method. This method was previously only
working correctly because boards using this display were configuring
the display INT pin using the pin control API prior to resetting the
display, so when the display was reset it would select the alt-addr
I2C address.
