We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.
This change was generated with the following Coccinelle SmPL patch:
@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@
-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)

Locking of config and doorbell operations should be done only if the
underlying hardware requires it.
This patch removes the global spinlocks from the rapidio subsystem and
moves them to the mport drivers (fsl_rio and tsi721), only to the
necessary places. For example, local config space read and write
operations (lcread/lcwrite) are atomic in all existing drivers, so there
should be no need for locking, while the cread/cwrite operations which
generate maintenance transactions need to be synchronized with a lock.
Later, each driver could chose to use a per-port lock instead of a
global one, or even more granular locking.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Add new Port Write handler registration interfaces that attach PW
handlers to local mport device objects. This is different from old
interface that attaches PW callback to individual RapidIO device. The
new interfaces are intended for use for common event handling (e.g.
hot-plug notifications) while the old interface is available for
individual device drivers.
This patch is based on patch proposed by Andre van Herk but preserves
existing per-device interface and adds lock protection for list
handling.

rmu needs to be freed before leaving the function in an error case.
A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

Usually, freescale rapidio endpoint can support one or two 1x or 4X
LP-Serial link interfaces, and rapidio message transactions can be
implemented by two message units. This adds the support of two
rapidio ports and initializes message unit 0 and message unit 1. And
these ports and message units can work simultaneously.

The Freescale PowerPC RapidIO controller consists of a RapidIO endpoint and
a RapidIO message unit(RMU). Or use RapidIO message manager(RMan) to
replace the RMU in DPAA architecture. Therefore, we should split the code
into two function modules according to the hardware architecture. Add new
struct for RMU module, and new initialization function to set up RMU
module. This policy is very conducive to adding new module like RMan, or
adding multi-ports or message units support.
