[PATCH] m32r: Update syscall macros for MMU-less targets

This patch is for updating m32r's MMU-less support.

Some legacy MMU-less m32r chips cannot return from a trap handler to the
right-hand side 16-bit halfword code of a 32-bit instrucion code pair, because
a "trap" instruction specification was expanded in M32R-II ISA.

This modification forces "trap" instructions to be placed in word alignment
location with a parallel "nop" code.
