AT91SAM4L: handle reset run/halt in SMAP
This is a remake of http://openocd.zylin.com/1966
originally written by Angus Gratton <gus@projectgus.com>
ATSAM4L has a "System Manager Access Port" (SMAP) that holds the CPU
in reset if TCK is low when srst (RESET_N) is deasserted.
Without this change any use of sysresetreq or srst locks the chip
in reset state until power is cycled.
A new function smap_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and SMAP reset is released then.
