nxp: mimxrt1170: add support for NXP's LinkServer

Browse source 
LinkServer is NXP's tool to flash and debug on MCU's.
This patch expands support for LinkServer to MIMXRT1170.

There is one limitation with flashing and debugging the SoC's seciond
core (COrtex M4) that will be addressed with a future submission.
