sunxi: H616: add LPDDR4 DRAM support
The H616 SoC family has support for several types of DRAM: DDR3,
LPDDR3, DDR4 and LPDDR4.
At the moment, the driver only supports DDR3 and LPDDR3 memory.
Let's extend the driver to support the LPDDR4 memory. This type
of memory widely used in device with T507(-H) SoC and new orangepi
zero3 with H618.
The compatibility with T507 is not yet complete, because there
is difference in the phy_init array.
The LPDDR4-2133 timings correspond to DRAM Rayson RS1G32LO4D2BDS-53BT
found on the NOR SPI from the Orangepi Zero 3 4GB.
