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.

platform: replace strict_strto*() with kstrto*()

The usage of strict_strtoul() and strict_strtol() is not preferred,
because strict_strtoul() and strict_strtol() are obsolete. Thus,
kstrtoul() and kstrtol() should be used.

hp_wmi: Fix unregister order in hp_wmi_rfkill_setup()

Register order is:
			wifi
			bluetooth
			wwan
			gps

So unregister order must be:
			gps
			wwan
			bluetiith
			wifi

But currently gps and wwan are swapped. Fix that.
Also fix goto links.

wmi: parse_wdg() should return kernel error codes

The current code returns a mix of acpi_status and kernel error codes.
It should just return kernel error codes.  There are already error paths
in this function which return -ENOMEM and that's what the caller
expects.
