[U-Boot] [PATCH v4 03/13] rockchip: dts: rk3399: Create initial rk3399-u-boot.dtsi

[Jagan Teki]

U-Boot always managed to use Linux devicetree files with respective
bindings, but on the other hand u-boot also has it's own u-boot specific
nodes or properties example u-boot,dm-pre-reloc which is required for
SPL_OF_CONTROL to allocate particular node.

It is always a better job to add these u-boot specific nodes and properties
into separate dts files which has an extension of -u-boot.dtsi This would
help to sync the devicetrees from Linux whenever required instead of adding
specific nodes.

So, create initial rk3399-u-boot.dtsi with sdmmc u-boot,dm-pre-reloc
property so-that the subsequent rk3399 boards can include the same
on their board dtsi files.
