When build Linux kernel, encounter the following warnings:

./arch/powerpc/sysdev/mpic_msgr.c:230:38: warning: cast removes address space '__iomem' of expression
./arch/powerpc/sysdev/mpic_msgr.c:230:27: warning: incorrect type in assignment (different address spaces)

The data type of msgr->mer and msgr->base are 'u32 __iomem *', but
converted to 'u32 *' and 'u8 *' directly and cause above warnings, now
instead of using a type cast, change the size of the pointer offset to fix
these warnings.

[...]

Applied to powerpc/next.
