This commit enables BM on: * A385-DB-AP - each port has its own pool for long and common pool for short packets, * A388-DB - to each port unique 'short' and 'long' pools are mapped, * A388-GP - same as above. Moreover appropriate entry is added to 'soc' node ranges, as well as "okay" status for 'bm' and 'bm-bppi' (internal SRAM) nodes.
