8348c259dd arm/pxa2xx: reorgazine SSP and SPI header files
The PXA-SPI driver relies on some files / defines which are arm specific
and are within the ARM tree. The CE4100 SoC which is x86 has also the
SPI core.
This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
include/linux where the CE4100 can access them.

This move got verified by building the following defconfigs:
   cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
   imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
   raumfeld_defconfig magician_defconfig

077de1ad5a [ARM] pxa: avoid NULL dereferencing in error handling of ssp.c
The assignments of res to the results of the two calls to
platform_get_resource make it impossible to use res in the error handling
code in the arguments to release_mem_region.

The semantic match that finds the former problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
expression E, E1;
identifier f;
statement S1,S3;
iterator iter;
@@

if ((E == NULL && ...) || ...)
{
 ... when != false ((E == NULL && ...) || ...)
     when != true  ((E != NULL && ...) || ...)
     when != iter(E,...) S1
     when != E = E1
(
 sizeof(E->f)
|
* E->f
)
 ... when any
 return ...;
}
else S3
