Ninad Palsule eb04c35da2 hw/fsi: Aspeed APB2OPB & On-chip peripheral bus 
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

An APB-to-OPB bridge enabling access to the OPB from the ARM core in
the AST2600. Hardware limitations prevent the OPB from being directly
mapped into APB, so all accesses are indirect through the bridge.

The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in
POWER processors. This now makes an appearance in the ASPEED SoC due
to tight integration of the FSI master IP with the OPB, mainly the
existence of an MMIO-mapping of the CFAM address straight onto a
sub-region of the OPB address space.

[ clg: - moved FSIMasterState under AspeedAPB2OPBState
       - modified fsi_opb_fsi_master_address() and
         fsi_opb_opb2fsi_address()
       - instroduced fsi_aspeed_apb2opb_init()
       - reworked fsi_aspeed_apb2opb_realize()
       - removed FSIMasterState object and fsi_opb_realize()
       - simplified OPBus
       - introduced fsi_aspeed_apb2opb_rw to fix endianness issue ]
