MLK-10176-4 imx: mx7: Add arch level support

Introduce a new cpu type MXC_CPU_MX7D and relevant functions for mx7d.
Implement the soc.c for various system level functions like:
temperature check, arch init, get mac fuse, boot mode get/apply, etc.

Additional, enable building imx common platform files for mx7d.
