Andy Shevchenko 49c0309626 pinctrl: baytrail: Do not add all GPIOs to IRQ domain
When DIRECT_IRQ_EN is set, the pin is routed directly to the IO-APIC bypassing
the GPIO driver completely. However, the mask register is still used to
determine if the pin is supposed to generate IRQ or not.

So with commit 3ae02c14d9 the IRQ core masks all IRQs (because of
handle_bad_irq()) the pin connected to the touchscreen gets masked as well and
hence no interrupts.

To make this all work as expected we do not add those GPIOs to the IRQ domain
that can actually propagate interrupts.

Fixes: 3ae02c14d9 ("pinctrl: intel: set default handler to be handle_bad_irq()")
