powerpc/xmon: Enable breakpoints on 8xx
[ Upstream commit 30662217885d7341161924acf1665924d7d37d64 ]
Since commit 4ad8622dc548 ("powerpc/8xx: Implement hw_breakpoint"),
8xx has breakpoints so there is no reason to opt breakpoint logic
out of xmon for the 8xx.
Fixes: 4ad8622dc548 ("powerpc/8xx: Implement hw_breakpoint")
