[RFC 11/19] interconnect: imx: Add imx_icc_get_bw and imx_icc_aggregate functions

[Abel Vesa]

The aggregate function will return whatever is the highest
rate for that specific node. The imx_icc_get_bw sets the
initial avg and peak to 0 in order to avoid setting them to
INT_MAX by the interconnect core.
