net: mvpp2: Fix hangs when starting some interfaces on 7k/8k

Armada 7K / 8K clock management has recently been reworked, see :

commit 2587c2bedb27 ("clk: mvebu: cp110: Fix clock tree representation")

I have been experiencing overall system hangs on MacchiatoBin when starting
the eth1 interface since then. It turns out some clocks dependencies were
missing in the PPv2 and xmdio driver, the clock rework made this visible.

This is the V2 series, that adds support for the missing 'MG Core clock' in
mvpp2, and fixes an issue with the error path for the axi_clk.

Thanks to Gregory Clement for finding the root cause of this bug.

V2 : Remove all DT patches from this series, they will be merged through
     the mvebu tree.
