powerpc/fsl: Added aliased MSIIR register address to MSI node in dts
The MSIIR register for each MSI bank is aliased to a different
address. The MSI node reg property was updated to contain this
address:
e.g. reg = <0x41600 0x200 0x44140 4>;
The first region contains the address and length of the MSI
register set and the second region contains the address of
the aliased MSIIR register at 0x44140.
