ACPI / video: Fix use_native_backlight selection logic

Commit 751109aad583 ("ACPI / video: Change the default for
video.use_native_backlight to 1") has changed the default for
use_native_backlight from 0 to 1, but instead of changing
use_native_backlight_dmi to true, and leaving use_native_backlight_param at -1,
it has changed use_native_backlight_param to 1.

This causes acpi_video_use_native_backlight() to always think that a value was
specified through the param, making it impossible to add a dmi based quirk
to force 0 now that the default is 1.

This fixes this by restoring the use_native_backlight_param default to -1, and
instead setting the use_native_backlight_dmi default to true.

ACPI / video: Add a disable_native_backlight quirk

Some laptops have a working acpi_video backlight control, and using native
backlight on these causes a regression where backlight control does not work
when userspace is not handling brightness key events. Disable native_backlight
on these to fix this.

ACPI / EC: Add msi quirk for Clevo W350etq

Clevo W350etq's EC will not produce GPE interrupt some time after
booting. The ACPI notify event won't trigger when the issue takes
place. After debugging, adding msi quirk for the machine can fix
the issue. This patch is to add msi quirk for the machine.

ACPI / LPSS: drop clkdev_name member from lpss_device_desc

It was used to provide the correct con_id for the dma
driver, but it's not needed. Even if the driver requests a
clock with the con_id, it still gets the correct clock. The
device name is enough to match a single clock.

PM / sleep: Fix test_suspend= command line option

After commit d431cbc53cb7 (PM / sleep: Simplify sleep states sysfs
interface code) the pm_states[] array is not populated initially,
which causes setup_test_suspend() to always fail and the suspend
testing during boot doesn't work any more.

Fix the problem by using pm_labels[] instead of pm_states[] in
setup_test_suspend() and storing a pointer to the label of the
sleep state to test rather than the number representing it,
because the connection between the state numbers and labels is
only established by suspend_set_ops().
