Change DEVICE_ACPI_HANDLE to ACPI_HANDLE for linux-3.13

The commit 3a83f992490f8235661b768e53bd5f14915420ac
"ACPI: Eliminate the DEVICE_ACPI_HANDLE() macro" from mainline removes
DEVICE_ACPI_HANDLE in favor of ACPI_HANDLE.

This patch makes bbswitch to use ACPI_HANDLE when available in order to
be built properly.
