ACPI: introduce module_acpi_driver() helper macro
Add a helper macro module_acpi_driver() which reduces the boilerplate code for ACPI drivers. This is similar what is done for other busses (PCI, SPI, I2C etc). Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
