platform/x86: alienware-wmi: Refactor LED control methods

Browse source

Both WMI devices handled by this module specify a distinct interface for
LED control. Previously this module handled this by dynamically adapting
arguments passed to wmi_evaluate_method() based on the `interface`
global variable.

To avoid the use of global variables, and enable the migration to
non-deprecated WMI methods, let the WMI drivers define upd_led and
upd_brightness operations, which completely replace
alienware_update_led() and wmax_brightness().

Also define alienware_wmi_command(), which serves as a wrapper for
wmidev_evaluate_method(). This new method is very similar to
alienware_wmax_command() but is WMI device agnostic.
