Subject: [PATCH] rockchip: rk3399: split nanopi-r4-rk3399 out of evb_rk3399
nanopi-r4-rk3399 board has multiple DDR types. Currently we don't have any code
are compatible with these devices. Since multiple DDR types is specific to
nanopi-r4-rk3399 board, split it into its own board file and add code
support here.

Subject: [PATCH] ram: rk3399: Add support for multiple DDR types
Move rockchip,sdram-params to named subnode to include
multiple sdram parameters, and then read the parameters
(by subnode name, first subnode or current node) before
rk3399_dmc_init().
