ARM: 6864/1: hw_breakpoint: clear DBGVCR out of reset
commit e89c0d7090c54d7b11b9b091e495a1ae345dd3ff upstream.
The DBGVCR, used for configuring vector catch debug events, is UNKNOWN
out of reset on ARMv7. When enabling monitor mode, this must be zeroed
to avoid UNPREDICTABLE behaviour.
This patch adds the zeroing code to the debug reset path.
