MIPS: Delete unused code in linux32.c

Browse Source 
The A() & AA() macros have been unused since commit 05e4396651
("[MIPS] Use SYSVIPC_COMPAT to fix various problems on N32"), which
switched to the more standard compat_ptr().

RLIM_INFINITY32, RESOURCE32() & struct rlimit32 have been present but
unused since the beginning of the git era.

Remove the dead code.

/* A() macro should be used for places where you e.g.
have some internal variable u32 and just want to get
rid of a compiler warning. AA() has to be used in
places where you want to convert a function argument
to 32bit pointer or when you e.g. access pt_regs
structure and want to consider 32bit registers only.
