The S/PDIF rxtx4 and rxtx6 clock inputs are "ESAI_HCKT" and "MLB clock",
respectively, according to the SoC documentation, and they are currently
mapped to clocks "esai" and "mlb".

However, they do not seem to actually work correctly. Testing on a
Cubox-i system with fsl_spdif driver forced to select one of those as
input will result in I/O errors on audio playback, which I believe means
missing clock signal.

Possibly the "ESAI_HCKT" and "MLB clock" refer to some other clocks
related to ESAI and MLB, or we are missing something else.

Since audio playback will not work if fsl_spdif selects these clocks
(which happens rarely), set the inputs do dummy clocks, at least for
now.

The rxtx2 clock of i.MX6 S/PDIF is currently set to "asrc" clock.
However, according to SoC documentation, rxtx2 is connected to
ASRC_EXT_CLK, a different external clock.

Testing on Cubox-i system seems to confirm that: when fsl_spdif is
forced to select rxtx2 as input clock, audio playback fails with an I/O
error.

Set rxtx2 to the dummy clock by default to prevent fsl_spdif from
selecting it.

The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs

"marvell,armada38x" by the "marvell,armada380" string.

This patch fixes two problems: -

1) The device tree isn't currently providing sti-ethclk which is
required by the dwmac glue code to correctly configure the ethernet
PHY clock speed.

This means depending on what the bootloader/jtag has
configured this clock to, and what switch/hub the board is plugged
into you most likely will NOT successfully negotiate a ethernet link.

2) The stmmaceth clock was associated with the wrong clock. It was
referencing the PHY clock rather than the interconnect clock which
clocks the IP.

This patch also brings us closer to not having to boot the upstream
kernel with the clk_ignore_unused parameter.
