So we need to disable our IRQ while suspended to enforce this. The code paths for devices with GPIOs for the int and reset pins already disable the IRQ the through goodix_free_irq(). This commit also disables the IRQ while suspended for devices without GPIOs for the int and reset pins. This fixes the i2c bus sometimes getting stuck after a suspend/resume causing the touchscreen to sometimes not work after a suspend/resume. This has been tested on a GPD pocked device.

Without this change sensor measurement stays on even though probe fails on these calls. This is maybe rare case, but causes constant power drain without any benefits when it happens.
