interconnect: qcom: msm8974: switch to the main icc-rpm driver

In preparation to restoring the ability of MSM8974 driver to work with
the modern kernels, switch the driver to the main icc-rpm set of helper
code.

As platform-specific workarounds, set the get_bw callback (returning 0)
to prevent initial setup from programming INT_MAX into the RPM (which
otherwise might hang the platform) and tell RPM programming code to
ignore -ENXIO errors from the firmware (until the QoS programming is
sorted out).
