thinkpad-acpi: fix issuing duplicated key events for brightness up/down
The tp_features.bright_acpimode will not be set correctly for brightness control because ACPI_VIDEO_HID will not be located in ACPI. As a result, a duplicated key event will always be sent. acpi_video_backlight_support() is sufficient to detect standard ACPI brightness control.
