Devicetree files in RK3399 platform is synced from Linux, like other
platforms does. Apart from these u-boot in rk3399 would also require
some u-boot specific node like dmc.
dmc node has big chunk of DDR timing parameters which are specific
to specific board, and maintained with rk3399-sdram*.dtsi.
So, create board specific -u-boot.dtsi files and move these sdram dtsi
files accordingly. This would help of maintain u-boot specific changes
separately without touching Linux dts(i) files which indeed easy for
syncing from Linux between releases.
These board specific -u-boot.dtsi can be extendible to add more u-boot
specific nodes or properties in future.

Add some U-Boot-specific settings. These should really go in the
*u-boot.dtsi file, but it seems that rk3399 does not use that yet.
