The SRAM on the PX30 is not big enough to hold multiple DDR configs so it needs to be selected during build. So far simply the DDR3 config was always selected and getting DDR4 or LPDDR2/3 initialized would require a code modification. So add Kconfig options similar to RK3399 to allow selecting the DDR4 and LPDDR2/3 options instead, while DDR3 stays the default as before.
