The PCM is a pseudo-device. It doesn't have any of it's own registers
or hardware. It rather acts as a layer of abstraction for DMA
transfers. Hence, instead of classifying it as a device in its own
right, we call the initialisation from the MSP driver.

When switching to common clock driver for ux500 this clock needs to
be handled as well. Before this clock was internally managed by the
clock driver itself.

Register both parts of the MSP driver from Device Tree so that they
are probed when Device Tree is enabled. Also, as there is platform
data involved, we ensure that there is allocated memory to place the
configuration into and that the correct information is extracted from
the DT binary.

Currently there is no out-of-memory error checking after attempting
to allocate memory for the ux500_msp or ux500_msp_i2s_drvdata data
structures. Instead we go about populating them regardless. This
patch applies the necessary error checking to prevent a panic.

Thought to be another merge error, board-mop500-msp.h has never existed
in the upstream kernel, only msp.h. This patch changes the include files
to match the existing file name.
