It seems that recent kernels have a shorter timeout when scanning for
ethernet phys causing us to hit a timeout on boards where the phy's
regulator gets enabled just before scanning, which leads to non working
ethernet.
A 10ms startup delay seems to be enough to fix it, this commit adds a
20ms startup delay just to be safe.
This has been tested on a sun4i-a10-a1000 and sun5i-a10s-wobo-i5 board,
both of which have non-working ethernet on recent kernels without this
fix.

It seems that the wifi chip is powered by both ldo3 and ldo4 tied
together and that using only one results in the wifi-chip dropping of
the USB bus sometimes.
Ideally we would have a proper way of modelling this (this is being
worked on), but currently we do not. This is not an issue since we need
to keep these regulators always-on anyways, due to these boards
crashing when ldo3/4 get turned back on after having been turned off.

The Wobo i5 top set box is a somewhat curious A10s based top set box,
it uses an AXP209 rather then the AXP152 usually used in combination
with the A10s. It has an ethernet phy connected to PORTD rather then
PORTA, and its built-in usb wifi is connected via the otg controller.
This commit adds a dts file adding support for this top set box.
