Subject: [PATCH v6 net-next 03/10] ARM: dts: armada-38x: enable buffer manager support on Armada 38x boards

From: Marcin Wojtas <mw@...ihalf.com>

Since mvneta driver supports using hardware buffer management (BM), in
order to use it, board files have to be adjusted accordingly. This commit
enables BM on:
* A385-DB-AP - each port has its own pool for long and common pool for
short packets,
* A388-ClearFog - same as above,
* 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.

[gregory.clement@...e-electrons.com: add suppport for the ClearFog board]
