ENGR00152755 MX6 Switch DRAM init script from plugin to DCD for emmc fastboot
ROM requires DCD table instead of plugin to initialize DRAM if emmc fastboot
mode is to be used. Therefore, switched the DRAM script from plugin to
DCD table. The DCD table created is based on the following RVD script:

When fastboot mode is used by ROM, the MMC_BOOT register of USDHC does not
get reset when RSTA bit is set by uboot driver. Therefore, need to write 0
to it manually during driver init. This brings USDHC out of fastboot mode,
allowing normal communication with emmc to proceed in uboot.
Changed comments for DLL delay to be more accurate.
