[PATCH v3 1/1] sunxi: H616: add LPDDR4 DRAM support

From: iuncuim 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 orangep
