The qcom-rng driver supports both ACPI and device tree based systems.
ACPI support was broken when the hw_random interface support was added.
This small series gets that working again.

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.

Changes since v2:
- Simplify ACPI fix based on what's done with other drivers (Brian)

Changes since v1:
- Use qcom_prng_ee_match_data instead of qcom_prng_match_data for the
  true skip_init to match previous behavior (Ernesto)
- Reordered patches so fix is first (Dmitry)

Brian Masney (2):
  crypto: qcom-rng: fix support for ACPI-based systems
  crypto: qcom-rng: rename *_of_data to *_match_data
