This commit enables BM on AXP-DB and AXP-GP in same manner - because number of ports on those boards is the same as number of possible pools, each port is supposed to use single pool for all kind of packets. Moreover appropriate entry is added to 'soc' node ranges, as well as "okay" status for 'bm' and 'bm-bppi' (internal SRAM) nodes.
