[PATCH v2] soc: qcom: geni: shield geni_icc_get() for ACPI boot

[Shawn Guo <shawn.guo@linaro.org>]

Currently, GENI devices like i2c-qcom-geni fails to probe in ACPI boot,
if interconnect support is enabled.  That's because interconnect driver
only supports DT right now.  As interconnect is not necessarily required
for basic function of GENI devices, let's shield geni_icc_get() call,
and then all other ICC calls become nop due to NULL icc_path, so that
GENI devices keep working for ACPI boot.

Changes for v2:
- Only shield geni_icc_get(), as all other ICC calls will become nop
  anyway due to NULL icc_path.
