ACPI: video: Use acpi_device_fix_up_power_children()
Commit 89c290ea7589 ("ACPI: video: Put ACPI video and its child devices
into D0 on boot") introduced calling acpi_device_fix_up_power_extended()
on the video card for which the ACPI video bus is the companion device.
This unnecessarily touches the power-state of the GPU itself, while
the issue it tries to address only requires calling _PS0 on the child
devices.
Touching the power-state of the GPU itself is causing suspend / resume
issues on e.g. a Lenovo ThinkPad W530.
Instead use acpi_device_fix_up_power_children(), which only touches
the child devices, to fix this.
