The devm_ioremap_resource() function doesn't return NULL, it returns
error pointers.

This makes the queue manager driver able to probe from the device
tree. It only needs to get a memory resource and two interrupts
and the platform device provides these as resources, so all is
pretty simple.

This makes the NPE driver able to probe from the device tree.
It only needs to get three memory resources and the plaform
device provide these, so all is pretty simple.

Instead of using hardcoded base address implicitly
obtained through <linux/io.h>, pass the physical base
for the QMGR block as a memory resource and remap
it in the driver.
Also pass the two IRQs as resources and obtain them
in the driver.
Use devm_* accessors and simplify the error path in the
process. Drop memory region request as this is done by
the devm_ioremap* functions.

These former inlines turn out to be unused in the kernel.
If they are needed in the future, they can be resurrected
by reverting or studying this commit.

These inline functions immediately exploit the static ioremaps
for the queue manager memory region. This does not work with
multiplatform where everything need to be dynamically remapped,
so get rid of these inlines and create new exports for those
used by other drivers.

Drop the memory request region business, this will
anyways be done by devm_* remapping functions.

Instead of registering everything related to the QMGR
unconditionally in the module_init() call (which will
never work with multiplatform) create a platform device
and probe the QMGR like any other device.
Put the device second in the list of devices added for
the platform so it is there when the dependent network
and crypto drivers probe later on.
This probe() path will not be taken unconditionally on
device tree boots, so remove the DT guard.

This moves the IXP4xx Queue Manager and Network Processing
Engine headers out of the <mack/*> include path as that is
incompatible with multiplatform.

The Network Processing Engine and Queue Manager are
versatile firmware components used by several IXP4xx
drivers.
Drivers are relying on getting access to these components
using <mach/*> headers which does not work with
multiplatform. We need to find a better place for the
drivers to live.
Let's first move them to drivers/soc and the start to
refactor a bit by passing resources and moving headers.
This patch introduce static IRQ assignments but that
will be fixed by later patches in this series.
