[PATCH] soc: qcom: geni: shield ICC calls 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 those ICC calls to get
GENI devices probe for ACPI boot.
