MLK-10600-1: mxc: sim: Add SIM IP driver support on the i.MX7d-12x12-arm2 platform.

This driver is based on the current code which runs the the EMV test on the i.MX258 platform.
Since there are still many cases that can't pass on the i.MX258 and i.MX7d platform. The
driver will need to be improved after per-test work. Just check in as a base code. There
would be definitly some timing improvement work to do in the future.
