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.

Fix a long standing bug with per device locking.

Each device has an associated spinlock for synchronizing access to
hardware and state information with the ISR.  A single hardware card has
one or more devices.

Bug: Non ISR code correctly acquires and releases the per device lock.
ISR incorrectly always acquires and releases the lock of the first device
on the card.

The decoupled and list based nature of the ISR and deferred processing
interaction allowed this to work in normal operation.  Exceptional events
like an application forcing hardware shutdown, reset, or reconfiguration
while active can trigger the bug.

Fixed ISR to acquire and release the per device lock.

One exception is manipulation of the GPIO card resource which is global
and effectively owned by the first device of the card.  Non-ISR access to
GPIO resource is changed to use lock of first device on card.
