RapidIO: Add workaround for erratum A-008116
Erratum A-008116 can cause a Serial RapidIO phyiscal or
logical/transport error interrupt (PINTn) that orginates
on port 2 is incorrectly reported as originating on port 1.
Valid workaround needed if using Serial RapidIO port 2.
Upon detection of a Serial RapidIO interrupt, each port's
LTLEDCSR and PnEDCSR registers must be read to determine
the port origin.
