[PATCH 5/11] Add M32R_MAX_REGISTER_SIZE

Max size set to 32bits, which I determined using regformats/reg-m32r.dat

Tested on a --enable-targets=all build using make check with board files
unix and native-gdbserver.

I do not have an M32R machine to test on.

Ok to commit?

Alan.

* m32r-tdep.c (m32r_push_dummy_call): Use M32R_MAX_REGISTER_SIZE.
* m32r-tdep.h (M32R_MAX_REGISTER_SIZE): Add.
