The proper pointer to be passed as argument to PTR_ERR() is
priv->icc_pdev.

[cw00.choi: Edit the patch title from 'imx' to 'imx-bus']

There is no single device which can represent the imx interconnect.
Instead of adding a virtual one just make the main &noc act as the
global interconnect provider.
The imx interconnect provider driver will scale the NOC and DDRC based
on bandwidth request. More scalable nodes can be added in the future,
for example for audio/display/vpu/gpu NICs.

Add initial support for dynamic frequency switching on pieces of the imx
interconnect fabric.
All this driver does is set a clk rate based on an opp table, it does
not map register areas.
