 -  Allow drivers to define ACPI address space ID
 -  Allow drivers to define total amount of IRQs per community

lynxpoint:
 -  Drop no-op ACPI_PTR() call
 -  Introduce helpers to enable or disable input
 -  Make use of for_each_requested_gpio()

merrifield:
 -  Add I²S bus 2 pins to groups and functions

This driver adds pinctrl/GPIO support for Intel Emmitsburg PCH. The
GPIO controller is based on the next generation GPIO hardware but still
compatible with the one supported by the Intel core pinctrl/GPIO driver.

Not all sourcefiles which end up including pinctrl-mtk-common-v2.h make use
of 'mtk_default_register_base_names' and there is nowhere we can place the
definition to void the need for __maybe_unused except its own headerfile,
which seems like overkill.  So instead we tell the compiler that it's okay
for it to be unused by some of the consumers.

Fixes the following W=1 kernel build warning(s):

We need to iterate over each pin in a group for a function and
disable higher priority mux configurations on the pin before finally
muxing the relevant function's signal. With the current debug output it
is hard to track what register output is relevant to which operation, so
break up the actions in the debug output by providing some more context.

Modify omap_gpio_set_config() to handle pin config bias flags by calling
gpiochip_generic_config().

The pin group for the gpio line must have the corresponding pinconf
properties:

PIN_CONFIG_BIAS_PULL_UP requires "pinctrl-single,bias-pullup"
PIN_CONFIG_BIAS_PULL_DOWN requires "pinctrl-single,bias-pulldown"

This is necessary for pcs_pinconf_set() to find the requested bias
parameter in the PIN_MAP_TYPE_CONFIGS_GROUP pinctrl map.
