icepick.cfg: add cancel reset bit to TAP register writes
The Agama family of devices (CC26x2/CC13x2) required an
additional bit to be set when adding the core's TAP into
the scan chain. The cancel reset bit 0x10000 tells the
ICEPick to take the bus out of reset so that the other
bits will take effect. This bit is a NOP on other devices
and ICEPicks, so the change shouldn't adversely affect
other devices.
