When removing prom.h include by of.h, several OF headers will no longer
be implicitly included. Add explicit includes of of_*.h as needed.

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.
