ENGR00136075 MX53: Add SMD board support

Add MX53 SMD support:
- Use DDR3 script for SMD board from Mike Kjar:
"Rita_init_LCB_CMOS.inc"
- Set the default CPU core frequency as 1GHZ.

The following functions are tested on SMD board:
- SD/MMC boot, read, write via SDHC1
- eMMC4.4 boot, read, write via SDHC3.
- SATA boot, read, write. To support SATA boot via internal
clock, please ensure the fuse "SATA_ALT_CLK_REF" was blown.
- FEC
- UART
- clk command
- iim command
