Make dell-wmi call ledtrig_kbd_backlight() when the keyboard-backlight
brightness changes.
This will allow userspace to monitor (poll) for brightness changes on
these LEDs caused by the hotkey.

Changes in v2:
-Use the new dell_smbios*notify functionality
Changes in v3:
-Simplify the if condition for calling led_notify_brightness_change
Changes in v4:
-Adjust for dell_smbios_*_notifier to dell_laptop_*_notifier rename
Changes in v5:
-Switch to new led-trigger based API for notifying userspace about
keyboard backlight brightness changes.
-This also drops the need for the custom dell_laptop_*_notifier code
