MIPS: Cavium: Add EDAC support.
Drivers for EDAC on Cavium. Supported subsystems are:
o CPU primary caches. These are parity protected only, so only error
reporting.
o Second level cache - ECC protected, provides SECDED.
o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will
will only initialize if ECC is enabled on a system so is safe to run on
non-ECC memory.
o PCI: Parity error reporting
Since it is very hard to test this sort of code the implementation is very
conservative and uses polling where possible for now.
