[PATCH v4 0/1] sunxi: H616: add LPDDR4 support

[Mikhail Kalashnikov]

From: iuncuim <iuncuim at gmail.com>

At the moment, the driver only supports DDR3 and LPDDR3 memory.
Add support for a new type DRAM.
These changes have been successfully tested by me with orangepi
zero3 4GB (DRAM: Rayson RS1G32LO4D2BDS-53BT).
This patch should be applied after this:

Changes from v3:
 * added LPDDR4 part for mctl_phy_read_training()
 * added the new part in mctl_phy_configure_odt() as LPDDR4 specific to
 avoid possible problems with existing devices

Changes from v2:
 * added default value for TPR6 parameter
 * added panic for unsupported DRAM types in switch/case conditions
 * added new line at the end of the timings file, changed the description
 * added a few small missing parts obtained from boot0

Changes from v1:
 * replaced the phy_init array with one compatible with opizero3
 * added DRAM TPR6 parameter
 * adaptation to new mctl_phy_configure_odt()
 * added timings for the board orangepi zero3 4GB
