ARM: hw_breakpoint: fix warnings generated by sparse

sparse doesn't like per-cpu accesses such as:

static DEFINE_PER_CPU(struct perf_event *, foo[MAXLEN]);
struct perf_event **bar = __get_cpu_var(foo);

and shouts quite loudly about it:

| warning: incorrect type in assignment (different modifiers)
|    expected struct perf_event **slots
|    got struct perf_event *[noderef] *<noident>

This patch adds casts to these sorts of assignments in hw_breakpoint.c
in order to silence the warnings.
