ACPI / video: Fix using an uninitialized mutex / list_head in acpi_video_handles_brightness_key_presses()
If acpi_video_handles_brightness_key_presses() was called before
acpi_video_register(), it would use the video_list mutex / list_head
uninitialized.
This patch fixes this by using DEFINE_MUTEX / LIST_HEAD when declaring
these, instead of initializing them runtime from acpi_video_register().
Fixes: 90b066b15eda "ACPI / video: Add a acpi_video_handles_brightness_key_presses() helper"
