[PATCH 4.19 067/131] net: dsa: b53: Fix ARL register definitions

[Greg Kroah-Hartman]

From: Florian Fainelli <f.fainelli@xxxxxxxxx>

[ Upstream commit c2e77a18a7ed65eb48f6e389b6a59a0fd753646a ]

The ARL {MAC,VID} tuple and the forward entry were off by 0x10 bytes,
which means that when we read/wrote from/to ARL bin index 0, we were
actually accessing the ARLA_RWCTRL register.

Fixes: 1da6df85c6fb ("net: dsa: b53: Implement ARL add/del/dump operations")
