Bug#824685: Ethernet not working - Cannot attach to PHY (error: -19)

[Fred F <frederik.vogelsang@gmail.com>]

Package: linux-image-4.5.0-2-armmp-lpae
Version: 4.5.3-2

Ever since linux-image 4.5 the network interface on my Cubietruck is
not working any more. The system log show this message:

[  182.543205] sun7i-dwmac 1c50000.ethernet: no regulator found
[  182.543431] sun7i-dwmac 1c50000.ethernet: no reset control found

[  182.814742] eth0: Could not attach to PHY
[  182.818809] stmmac_open: Cannot attach to PHY (error: -19)

With linux-image-4.4.0-1-armmp-lpae and earlier version ethernet is
working properly.

See [1] for details. Reverting commit 88f8b1b is supposed to fix the problem.
