MIPS: Enable ptrace hw watchpoints on MIPS R6 

HARDWARE_WATCHPOINTS isn't being enabled for CPU_MIPSR6, even though it
has an identical hardware watchpoint interface to CPU_MIPSR2, which
prevents ptrace watchpoints from being loaded when executing a ptraced
process even though the watchpoints are described in /proc/cpuinfo.

Enable HARDWARE_WATCHPOINTS for CPU_MIPSR6 too.
