New GPIO IRQs are allocated and mapped dynamically by default when GPIO IRQ infrastructure is used by cherryview-pinctrl driver. This causes issues on some Intel platforms [1][2] with broken BIOS which hardcodes Linux IRQ numbers in their ACPI tables. On such platforms cherryview-pinctrl driver should allocate and map all GPIO IRQs at probe time. Side effect - "Cannot allocate irq_descs @ IRQ%d, assuming pre-allocated\n" can be seen at boot log. NOTE. It still may fail if boot sequence will changed and some interrupt controller will be probed before cherryview-pinctrl which will shift Linux IRQ numbering (expected with CONFIG_SPARCE_IRQ enabled).
