Subject: [PATCH] [acpi driver model] Add macro helpers for drivers

- Create declaration macros for reducing the busywork of defining a driver.
- declare_acpi_driver(name, ...) declares
	- a struct acpi_device_driver
	- An ID structure (an array of char * ids passed the macro)
	- The init/exit functions, along with module_{init,exit}
	  declarations
