Add the sdram driver for PX30 to support ddr3, ddr4, lpddr2 and lpddr3.
For TPL_BUILD, the driver implement full dram init and without DM
support due to the limit of internal SRAM size.
For SPL and U-Boot proper, it's a simple driver with dm for get
dram_info like other SoCs.

The J721E DDR subsystem comprises DDR controller, DDR PHY and wrapper
logic to integrate these blocks in the device. The DDR subsystem is
used to provide an interface to external SDRAM devices which can be
utilized for storing program or data. Introduce support for the
DDR controller and DDR phy within the DDR subsystem.

Right now sdram drivers in rockchip SoC are built based
on the SoC configs which may not be an adequate solutions
while adding common or debug driver.
So, add meaningful Kconfig options start with rk3399.

K3 based AM654 devices has DDR memory subsystem that comprises
Synopys DDR controller, Synopsis DDR phy and wrapper logic to
intergrate these blocks into the device. This DDR subsystem
provides an interface to external SDRAM devices. Adding support
for the initialization of the external SDRAM devices by
configuring the DDRSS registers and using the buitin PHY
routines.

Add support for a driver which sets up DRAM and can return information about
the amount of RAM available. This is a first step towards moving RAM init
to driver model.
