[PATCH net-next v2 4/7] net: ipa: use bulk operations to set up interconnects

[Alex Elder <elder@linaro.org>]

Use of_icc_bulk_get() and icc_bulk_put(), icc_bulk_set_bw(), and
icc_bulk_enable() and icc_bulk_disable() to initialize individual
IPA interconnects.  Those functions already log messages in the
event of error so we don't need to.
