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.

vcc5v0. 3.0V/3.3V and 5.0V are commonly used voltages in Allwinner
devices. These dummy regulators provide a stand-in when bindings that
require one, but the real regulator is not supported yet.
Since these are no longer needed, we can drop the include file.

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.

Retire this venerable driver as the basic support is now in the
generic st-sensors accelerometer driver.
There are a few missing features in the new driver:
* Threshold events.
* Access to the calibration adjustment registers (patch shortly)
In exchange it brings a cleaner and more maintainable code base that actually
gets tested more than once every few years. I'll actually be suprised
if anyone other than me has a board with one of these on that is running
an up to date kernel.

Time to finally kill off the venerable (it was one of my first drivers)
lis3l02dq driver in favour of adding support in the st sensors framework.
This does loose us the event support that driver always had, but I think
that will reappear at some point and in the meantime the maintenance
advantages of dropping the 'special' driver for this one part outweigh
the issues.
It's worth noting this part is ancient and I may well be the only person
who still has any on hardware running recent kernels.
It has a few 'quirks'.
- No WAI register so that just became optional.
- A BDU option that really does block updates. Completely.
Whatever you do, you don't get any more data with it set.
It is documented the same as more modern parts but I presume they
are actually clearing for updates after a read of both bytes!
- Fixed scale.
- It's too quick. Even at slowest rate (280Hz) I can't read out fast
enough on my board (stargate 2) to beat new data coming in. Linus'
repeat read patch doesn't help in this case. It just means I get 10
readings before dying... So in reality this will get used with
software triggers only unless someone has this long out of production
device on a quick board.
