From: iuncuim <iuncuim@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 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
