This patch removes platform device registration of all 4 MSP
devices. It also takes care of all redundant infrastructure now
that each of the ux500 audio components have been Device Tree
enabled.

In this patch we prevent MOP500 driver registration from platform
code and rely solely on Device Tree to do the probing for us.

It isn't currently possible to pass all platform specific configuration
though Device Tree. Thinks like device names used in the clock
infrastructure, call-backs and DMA information have to be passed in via
AUXDATA structures and the MSP is no exception. Here we're passing DMA
settings.

We've done this before and it worked well last time. Here we're
duplicating a complex registration function to ease the process
of enabling it for Device Tree. As there are quite a few steps
taken during the registration process, it makes sense to break
them up into more manageable chunks. This patch will aid us.

This patch contains a couple of general MSP clean-ups pertaining to
layout changes and changing functions to be void instead of int instead
of regardlessly returning '0'.

In the initial submission of the MSP driver msp1 and msp3's associated
pinctrl mechanism was passed back to platform code using a plat_init()
call-back routine, but it has no place in platform code. The MSP driver
should set this up for the appropriate ports. Instead we use a use_pinctrl
identifier which is passed from platform_data/Device Tree which indicates
which ports should use pinctrl.

The platform attempts to register platform device 'snd_soc_u8500'
which doesn't actually exist. Here we change the reference to the
correct one 'snd_soc_mop500'.

The MSP platform data callbacks use the old custom callbacks to
set the state of the pins, switch over to using pinctrl.

Alter the db8500_add_msp_i2s() calls to return a struct
platform_device * pointer, not an integer. We nee the pointer
to obtain a pinctrl handle.
