The baseboard of the Logic PD i.MX6 development kit has a power
button routed which can both power down and power up the board.
It can also wake the board from sleep. This functionality was
marked as disabled by default in imx6qdl.dtsi, so it needs to
be explicitly enabled for each board.
This patch enables the snvs power key again.

Some USB peripherals draw more power, and the sourcing regulator
take a little time to turn on. This patch fixes an issue where
some devices occasionally do not get detected, because the power
isn't quite ready when communication starts, so we add a bit
of a delay.

The main 3.3V regulator sources a series of additional regulators.
This patch adds a small delay, so when the 3.3V regulator comes
on it delays a bit before the subsequent regulators can come on.
This reduces the inrush current a bit on the external DC power
supply to help prevent a situation where the sourcing power supply
cannot source enough current and overloads and the kit fails to
start.

The original submission had functional audio out and was based
on reviewing other boards using the same wm8962 codec. However,
the Logic PD board uses an analog microphone which was being
disabled for a digital mic. This patch corrects that and
explicitly sets the gpio-cfg pins all to 0x0000 which allows the
analog microphone to capture audio.

Commit 6d4cd041f0 ("net: phy: at803x: disable delay only for RGMII mode")
exposed an issue on imx DTS files using AR8031/AR8035 PHYs.
The end result is that the boards can no longer obtain an IP address
via UDHCP, for example.
Quoting Andrew Lunn:
"The problem here is, all the DTs were broken since day 0. However,
because the PHY driver was also broken, nobody noticed and it
worked. Now that the PHY driver has been fixed, all the bugs in the
DTs now become an issue"
To fix this problem, the phy-mode property needs to be "rgmii-id", which
has the following meaning as per
Documentation/devicetree/bindings/net/ethernet.txt:
"RGMII with internal RX and TX delays provided by the PHY, the MAC should
not add the RX or TX delays in this case)"
Tested on imx6-sabresd, imx6sx-sdb and imx7d-pico boards with
successfully restored networking.
Based on the initial submission from Steve Twiss for the
imx6qdl-sabresd.

The EVM consists of a system on module (SOM) and baseboard, and LCD.
This patch adds a DTSI file for the SOM and baseboard separately,
then a wrapper to combine them and specify processor type and a
LCD information.
