825ab6b406 driver: ddr: Refine the ddr init driver on imx8m 
Refine the ddr init driver to make it more reusable for different
DDR type(LPDDR4, DDR4 & DDR3L). So we can reduce some redundant
code.

28cb058ff7 ddr: imx8m: fix ddr firmware location when enable SPL OF 
With CONFIG_SPL_OF_CONTROL, the device tree will be padded to
end of the u-boot-spl-nodtb.bin, however we also put
the ddr firmware file to this location, so need to adapt
the code with SPL OF and align to 4 bytes to ease copy firmware.
