[ Upstream commit cd7cd5b716d594e27a933c12f026d4f2426d7bf4 ]
PPD has only one ACHC device, which effectively is a Kinetis
microcontroller. It has one SPI interface used for normal
communication. Additionally it's possible to flash the device
firmware using NXP's EzPort protocol by correctly driving a
second chip select pin and the device reset pin.

A quoted label reference doesn't expand to the node path and is taken as
a literal string. Dropping the quotes can fix this unless the baudrate
string is appended in which case we have to use the alias.
At least on VF610, the problem was masked by setting the console in
bootargs. Use the alias syntax with baudrate parameter so we can drop
setting the console in bootargs.

The 'num-chipselects' property is not a valid property according
to Documentation/devicetree/bindings/spi/fsl-imx-cspi.txt, so
let's remove it.

Single child nodes in OF graph don't need an address and now dtc will
warn about this:
Warning (graph_child_address): /soc/aips@50000000/ldb@53fa8008/lvds-channel@0: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary
Since the LDB should always have an output port, fix the warning by
adding the output port, 2, to the DT.

Lots of i.MX boards use the SGTL5000 codec, but not all get the warning
because only some reference the codec with "sound-dai" property. However,
the codec should always provide #sound-dai-cells regardless, so fix all
the occurrences.
