Subject: [PATCH v3 0/3] ACPI 5 support for GPIO, SPI and I2C

This is a third version of the series. I've based these on top of Rafael's
"simplify glueing ACPI handles to physical nodes" seen here:

	https://lkml.org/lkml/2012/11/19/588

There is a dependency to linux-pm tree and to the above patches so I
propose to merge these via that same tree.

Changes to v2:
	- drop the ACPI ->find_device() glue magic in preference of the new
	  simplified mechanism where we just assign the ACPI handle
	- correct the IRQ resource handling to take the first resource and
	  skip the rest
	- moved declaration of acpi_i2c_register_devices() to i2c.h instead
	  of having a separate header for a single function
	- added acpi_node to struct i2c_board_info (analoguous to of_node).

Changes to the original version:
	[gpio]
	- CONFIG_GPIO_ACPI instead of CONFIG_ACPI_GPIO
	- removed redundant test in acpi_gpiochip_find()

	[spi and i2c]
	- switched to use ACPI centralized _CRS evaluation framework
	  introduced by Rafael 
	- dropped request_module() call
	- dropped the acpi_enumerate_spi/i2c_device()
	- added required includes and dropped <linux/acpi.h> from
	  acpi_i2c.h
