ACPI: button: Rework device verification during probe
Instead of manually comparing the primary ID of the device (retuned
by _HID) with each of the device IDs supported by the driver, use
acpi_match_acpi_device() (which includes the ACPI companion device
pointer check against NULL) and store the ACPI button type as
driver_data in button_device_ids[], which allows a multi-branch
conditional statement to be replaced with a switch () one. However,
to continue preventing successful probing of devices that only have
one of the supported device IDs in their _CID lists, compare the
matched device ID with the primary ID of the device and return an
error if they don't match.
No intentional functional impact.
