Remove h8300_print_float_info

In infcmd.c:print_float_info, if the architecture doesn't have gdbarch
method print_float_info implemented and doesn't float reggroup, GDB
will prints "No floating-point info available for this processor."
The h8300 port doesn't have float registers, and don't need to
implement print_float_info.  This patch is to remove it.
