crypto: qcom-rng - fix support for ACPI-based systems

The qcom-rng driver supports both ACPI and device tree-based systems.
ACPI support was broken when the hw_random interface support was added.
Let's go ahead and fix this by adding the appropriate driver data to the
ACPI match table, and change the of_device_get_match_data() call to
device_get_match_data() so that it will also work on ACPI-based systems.

This fix was boot tested on a Qualcomm Amberwing server (ACPI based) and
on a Qualcomm SA8775p Automotive Development Board (DT based). I also
verified that qcom-rng shows up in /proc/crypto on both systems.
