target/riscv/debug.c: use wp size = 4 for 32-bit CPUs

The mcontrol select bit (19) is always zero, meaning our triggers will
always match virtual addresses. In this condition, if the user does not
specify a size for the trigger, the access size defaults to XLEN.

At this moment we're using def_size = 8 regardless of CPU XLEN. Use
def_size = 4 in case we're running 32 bits.
