The audio unit of Marvell Armada38x SoC is similar to the ones comprised by
other Marvell SoCs (Kirkwood, Dove and Armada 370). Therefore KW audio
driver can be used to support it and this commit adds new compatible string
to identify Armada 38x variant.
Two new memory regions are added: first one for PLL configuration and
the second one for choosing one of audio I/O modes (I2S or S/PDIF).
For the latter purpose a new optional DT property is added ('spdif-mode').
kirkwood-i2s driver is extended by adding a new init function for Armada
38x flavor and also a routine that enables PLL output (i.e. MCLK)
configuration.

Make the declaration const too.

There is no hardware restriction requiring a minimum of 8 periods, or
a minimum of 2048 bytes in a period. Let's drop these values so that
userspace has more flexibility in choosing these parameters.

Merge these two structures together; nothing other than the I2S and
DMA driver makes use of struct kirkwood_dma_data, and it's not like
struct kirkwood_dma_data is really just used to convey DMA specific
data to the backend; it's more a general shared structure between the
two halves.
This will later allow kirkwood-dma.c and kirkwood-i2s.c to be merged
together.

Some platforms provide an external clock which can be used to allow
other sample rates to be selected. Provide support for this.
