[PATCH 05/30] bsd-user/arm/arget_arch_cpu.h: Move EXCP_DEBUG and EXCP_BKPT together

[Warner Losh]

Implement EXCP_DEBUG and EXCP_BKPT the same, as is done in
linux-user. The prior adjustment of register 15 isn't needed, so remove
that. Remove a redunant comment (that code in FreeBSD never handled
break points).
