This initializes the RapidIO controller driver using addresses and
interrupt numbers obtained from the firmware device tree, rather than
using hardcoded constants.

The original RapidIO driver suppose there is only one mpc85xx RIO controller
in system.  So, some data structures are defined as mpc85xx_rio global, such
as 'regs_win', 'dbell_ring', 'msg_tx_ring'.  Now, I changed them to mport's
private members.  And you can define multi RIO OF-nodes in dts file for multi
RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in
Freescale's silicon.  And the mport operation function declaration should be
changed to know which RapidIO controller is target.

The driver is suitable for the Freescale MPC8641 processor as well as
85xx processors, so this changes the mpc85xx prefix to fsl.

Do just enough to move the RapidIO support code for 85xx over from arch/ppc
into arch/powerpc and make it still build.
