Now that we can handle the generic pinctrl bindings, convert our DT to it.

The allwinner,pull property set to NO_PULL was really considered our
default (and wasn't even changing the default value in the code).
Remove these properties to make it obvious that we do not set anything in
such a case.

The allwinner,drive property set to 10mA was really considered as our
default. Remove all those properties entirely to make that obvious.

Enable the otg/drc usb controller on the Marsboard A10.
Similar to Cubieboard, the 5V of the otg is directly connected to the
general 5V, so we only use the id pin.

The A10 has a few SRAM that can be mapped either to a device or to the CPU,
with the mapping being controlled by a SRAM controller.
Add the SRAM controller, the SRAM that it drives and the section that can
be used by the various devices.

The pinctrl groups for SPI until now were also adding the chip selects in
the SPI pinctrl group.
This was causing a few issues, since a board was forced to use a random
number of chipselects, even though it might use one of these chip selects
for another pin.
The number of chipselects defined was also not the same from one group to
another because of different needs at the time these groups have been
introduced, resulting in no clear view from the board DTS on what exactly
is being muxed, which even might change in the future.
Solve this by creating different pinctrl groups for the chipselects and the
standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.

The FSF address triggers a warning on checkpatch, saying that the FSF
license is already present in the Linux source code, and that it has
already changed in the past.
Remove it from our DT, as suggested.

Add UART aliases and stdout-path property for all the Allwinner boards so that
we won't have to rely on the bootargs' console= value, while working with
legacy bootloaders.
While we're at it, also remove the mentions of earlyprintk in the bootargs,
that will remove our default bootargs entirely, and allow the kernel to boot on
a system even if DEBUG_LL is configured for another system.

The Marsboard A10 is a A10 based development board with 1G RAM, 1G NAND,
micro SD card slot, SATA 2.0 socket, 10/100 ethernet, mini HDMI port,
1 USB OTG port and 2 USB 2.0 ports. Board does not use the AXP209 pmic,
it does not have a pmic at all.
Board also have 2 expansion 70 pin headers.
