Second version of the set that changes I2C and SPI slave device names
to be generated from stable ACPI device names on ACPI 5 based systems
instead of using bus numbers which could change.

Slave device name change goes as

	"x-00yz" -> "i2c-INTABCD:ij"
	"spix.y" -> "spi-INTABCD:ij"

This version adds patch to include/acpi/acpi_bus.h that allow us to
remove #if IS_ENABLED(CONFIG_ACPI) checks that were added in the
first version.

Set goes on top linux-pm/linux-next commit e56b4d2.

First version here:

Jarkko Nikula (3):
  ACPI: Expose struct acpi_device and acpi_bus_get_device() to non-ACPI
  i2c: Use stable dev_name for ACPI enumerated I2C slaves
  spi: Use stable dev_name for ACPI enumerated SPI slaves
