acpi - Use KOBJ_GPRI_ACPI driver priorities for ig4 and gpio_intel.
* Since we currently don't handle the ACPI _DEP methods appropriately,
use the "global priority hack" from
5025fc65cd2448de8a5b7295c9936b473a7b0194 to enforce that ig4 and
gpio_intel attach before various ACPI namespace devices.
* This uses the KOBJ_GPRI_ACPI+1 and KOBJ_GPRI_ACPI+2 driver global priority
levels for important ACPI drivers, which may have to attach before other
ACPI devices can be used.
* This also adds the KOBJ_GPRI_ACPI global priority level to the sdhci_acpi
driver declaration.
