[ Upstream commit 0c9fdcdba68208270ae85d39600ea97da1718344 ]
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.
