Replace the single global destination ID counter with per-net allocation
mechanism to allow independent destID management for each available
RapidIO network. Using bitmap based mechanism instead of counters allows
destination ID release and reuse in systems that support hot-swap.

Modify handling of device lists to resolve issues caused by using single
global list of RIO devices during enumeration/discovery. The most common
sign of existing issue is incorrect contents of switch routing tables in
systems with multiple mport controllers while single-port configuration
performs as expected.

Modify RapidIO mport device name assignment to include device name of PCIe
side of Tsi721 bridge. The new name format is intended to provide
definitive reference between RapidIO and PCIe sides of the bridge in
systems with multiple Tsi721 bridges.

Detects RIO link to the already enumerated device and properly sets links
between device objects. Changes to the enumeration/discovery logic:
1. Use Master Enable bit to signal end of the enumeration - agents may
start their discovery process as soon as they see this bit set
(Component Tag register was used before for this purpose).
2. Enumerator sets Component Tag (!= 0) immediately during device
setup. This allows to identify the device if the redundant route
exists in a RIO system.

This set of RapidIO patches extends support for standard error recovery
mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and
CPS-1616. Implementation of the standard error-stopped state recovery
mechanism (as defined by the RapidIO specification) is required for the
new switches.
Version 2 of this set of patches addresses received comments and fixes an
error notification setup issue found in the idt_gen2.c after the first
version was released.
This patch:
Make RapidIO devices appear in /sys/devices/rapidio directory instead of
top of /sys/devices directory.
