To enable DM support in SPL, some necessary nodes must be reserved for
serial, clk, sysreset and other drivers.
This patch adds u-boot,dm-pre-reloc for these nodes.

Please don't add these U-Boot specific properties into these dts/dtsi
files. The preferred way is to create a new dtsi file with the U-Boot
specific additions. This will get included automatically in the build
process. Please see this file for example:
arch/arm/dts/mt7622-u-boot.dtsi
This will also enable us to stay in sync with the Linux DT files.
