m32r: Define THREAD_SIZE only once.
Previously, m32r's asm/thread_info.h defined THREAD_SIZE differently for assembly and C code; now that PAGE_SIZE is usable from assembly, these can be combined. Also, m32r's asm/processor.h redefines THREAD_SIZE to the same value; remove this redundant definition.
