[PATCH 2/2] goldfish: Enable ACPI-based enumeration for goldfish battery

[Alan <alan@linux.intel.com>]

From: Yu Ning <yu.ning@intel.com>

Besides adding ACPI bindings to the goldfish battery driver, modify the
ACPI driver to inform it that goldfish battery is a platform device.
The latter step is necessary with kernel 3.16 or newer.
