Anton Johansson d447a624d0 sysemu/hvf: Use vaddr for hvf_arch_[insert|remove]_hw_breakpoint
Changes the signature of the target-defined functions for
inserting/removing hvf hw breakpoints. The address and length arguments
are now of vaddr type, which both matches the type used internally in
accel/hvf/hvf-all.c and makes the api target-agnostic.
