Zbigniew Bodek 595f8a5905 Introduce support for HW watchpoints and single stepping for ARMv6/v7 
Allows for using hardware watchpoints for 1, 2, 4, 8 byte long addresses.
The default configuration of watchpoint is RW but code allows to select
RO or WO and X.
Since debugging registers are per-CPU (CP14) the watchpoint is set on
the CPU that was lucky (or not) to enter DDB.

HW breakpoints are used to perform single step in KDB.
When HW breakpoint is enabled all watchpoints are temporary disabled
to avoid recursive abort on both watchpoint and breakpoint.
In case of branch, the breakpoint is set to both - next instruction
and possible branch address. This requires at least 2 breakpoints
supported in the CPU however this is a must for ARMv6/v7 CPUs.
