3312eca519 MIPS: Octeon: mangle-port: fix build failure with VDSO code 
Commit 1685ddbe35 ("MIPS: Octeon: Changes to support readq()/writeq()
usage.") added bitwise shift operations that assume that unsigned long
is always 64-bits. This broke the build of VDSO code, as it gets compiled
also in "faked" 32-bit mode. Althought the failing inline functions are
never executed in 32-bit mode, they still need to pass the compilation.
Fix by using 64-bit types explicitly.

The patch fixes the following build failure:

1685ddbe35 MIPS: Octeon: Changes to support readq()/writeq() usage. 
Update OCTEON port mangling code to support readq() and
writeq() functions to allow driver code to be more portable.
Updates also for word and long function pairs. We also
remove SWAP_IO_SPACE for OCTEON platforms as the function
macros are redundant with the new mangling code.
