The blue led on the Mele M9 is wired to light up as soon as the board
has powered (it will be on while the gpio is still in input / floating
mode), also its location on the top-set box clearly signals "power led".

Until now we've been treating this as a generic usr function led, which
means that when you plug power into the top-set box, the power-led lights
and then turns off as soon as the kernel loads, which looks wrong.

This renames the led from m9:blue:usr to m9:blue:pwr and marks
it as default on, fixing this.

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.

require one, but the real regulator is not supported yet.

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 BPI-M2+ is an H3 development board. It is a smaller form factor than
the original BPI-M2, with the new H3 SoC.

It has 1GB DRAM, 8GB eMMC, a micro SD card slot, HDMI output, 2 USB
host connector and 1 USB OTG connector, an IR receiver, WiFi+BT based
on Ampak AP6212.

The board also has a 3 pin header for (debug) UART, a 40 pin GPIO header
based on the Raspberry Pi B+, but the peripheral signals are not the
same, and an FPC connector for connecting BPI's camera.
