This removes <mach/hardware.h> and <mach/db8500-regs.h>
from the Ux500, merging them into the local include
"db8500-regs.h" in mach-ux500. There is some impact
outside the ux500 machine, but most of it is dealt with
in earlier patches.

Contains portions of a clean-up patch from Arnd Bergmann.

This header file only contains platform data structure definitions,

Some ux500_msp_i2s patches clashed with:

b18e93a4
ASoC: ux500_msp_i2s: better use devm functions and fix error return code

... leaving the driver uncompilable. This patch fixes the
issues encountered.

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.

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.

Remove unnecessary calls to devm_kfree and replace iounmap by devm_iounmap
(and use resource_size for the third argument).  These changes make it
possible to remove the error-handling code at the end of
ux500_msp_i2s_init_msp, and all of the gotos become direct returns.

In the case of the second call to devm_kzalloc, the return variable ret was
not initialized.  Here it is changed to a direct return of -ENOMEM.

A simplified version of the semantic match that finds the second problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

// </smpl>

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
