[PATCH v1] Bluetooth: btintel_pcie: Allow COMPILE_TEST without ACPI

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

The driver only uses ACPI for the product reset method, so make that
depend on CONFIG_ACPI and allow the driver with COMPILE_TEST, so it is
build tested on architectures without ACPI as well, such as User Mode
Linux. Without ACPI the reset method reports it is not supported, as it
does when the device has no ACPI handle.
