Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`
Some unnecessary changes were manually fixed.

Pretty much any node can have a status property, so it doesn't need to
be in examples.
Converted with the following command and removed examples with SoC and
board specific splits:
git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

H3 SPI has same architecture as A31 except FIFO capacity.
To configure the buffer size separately, compatible property should be
different. Optional DMA specifiers and example are added.

The Allwinner A31 has a new SPI controller IP compared to the older Allwinner
SoCs.
It supports DMA, but the driver only does PIO for now, and DMA will be
supported eventually.
