[PATCH V2 3/7] riscv: dts: binman: add condition for opensbi os boot

[Randolph]

Add condition for OpenSBI OS boot mode, by default it is not enabled.
By default, binman creates the output file u-boot.itb.
If SPL_OPENSBI_OS_BOOT is enabled, linux.itb will be created
after compilation instead of the default u-boot.itb.
