Subject: [PATCH v1 5/6] ACPI: acpi_video: Rename ACPI device instances from device to adev

Since transformation from ACPI driver to platform driver there are
two devices on which the driver operates - ACPI device and platform
device.  For the sake of reader this calls for the distinction in
their naming, to avoid confusion. Rename relevant ACPI devices to adev,
as corresponding platform devices are called pdev.
