Certain functionality or its implementation in System76 EC firmware may
be different to the proprietary ODM EC firmware. Introduce a new bool,
`has_open_ec`, to guard our specific logic. Detect the use of this by
looking for a custom ACPI method name used in System76 firmware.

Managed devices do not need to be explicitly unregistered or freed, as
this is handled by devres. Drop the call to input_free_device.

input_free_device only needs to be called if input_register_device
failed, not in all error cases. Per devm_input_allocate_device
documentation, managed devices do not need to be explicitly unregistered
or freed, so do not add any other cleanup for the device.

Create the attribute groups for kb_led_color and set the `groups` field
in kb_led. While touching it, also change its show method to use
sysfs_emit() instead of sprintf().
