Subject: [PATCH] platform samsung-q10: use ACPI instead of direct EC calls

This patch changes the Samsung Q10 backlight driver to use ACPI methods
(the same ones as triggered by the brightness up/down function keys)
instead of direct EC calls. The advantage is that the brightness setting
is not lost on shutdown.
