ACPI: button: remove button->device pointer

We no longer need a pointer from struct acpi_button back to the
struct acpi_device.  Everywhere we used that pointer, we either
already have, or can easily get, the acpi_device pointer without
using the copy from acpi_button.  So this patch removes the
structure element.
