ENGR00124954 MX50: init sys by ROM plug-in feature
Use ROM plug-in feature to init DDR and re-config PLL1 to
800Mhz due to ROM set it to 799Mhz. Plug-in has the following benifit
from ROM team comments,
1. DCD size limitation issue, plugin can be the size of OCRAM
free space region which is 72KB.
2. Safe environment to re-configure PLL1 (without impacting SDRAM)
as the plugin runs from OCRAM. This could get around the issue
of some boards running with ARM @ 192MHz due to the incorrect
GPIO configuration for Low Power Boot.
3. Ability to have one bootloader binary for both LPDDR1 & LPDDR2 platforms.
