armv8/fsl-lsch3: partition stream IDs

Browse source 
Stream IDs on ls2085a devices are not hardwired and are
programmed by sw.  There are a limited number of stream IDs
available, and the partitioning of them is scenario dependent.
This header defines the partitioning between legacy, PCI,
and DPAA2 devices.

* On LS2085 stream IDs are programmed in AMQ registers (32-bits) for
* each of the different bus masters. The relationship between
* the AMQ registers and stream IDs is defined in the table below:
* AMQ bit streamID bit
* ---------------------------
* PL[18] 9
* BMT[17] 8
* VA[16] 7
* [15] -
* ICID[14:7] -
* ICID[6:0] 6-0
