[PATCH 2/4] ARM: dts: meson8b: extending ethernet controller description

[ingrassia@epigenesys.com (Emiliano Ingrassia)]

This patch adds ethernet controller pin description and extend its
attributes in the relative node.

Signed-off-by: Emiliano Ingrassia <ingrassia@epigenesys.com>

This patch corrects the meson8b-dwmac reg attributes updated by the previous
2/4 patch (450a483abe07f8d903c6cb74091592743975a8eb).
The second addresses range, taken from S805 (aka Meson8b) SoC manual,
was not correct.

Please, apply this patch and discard the previous
(450a483abe07f8d903c6cb74091592743975a8eb).
