dtc: introduce label relative path references
Since introduction of OF_UPSTREAM flag, U-Boot's dtc must be able
to compile Kernel's device tree.
Since kernel commit 7de129f5389b ("ARM: dts: stm32: stm32mp151a-prtt1l:
Fix QSPI configuration"), label relative path references has been
introduced. These label relative path references is not supported
by current U-Boot dtc version 1.5.0: (see mailing list discussion [1]).
In order to support such label relative patch references
adds following commit from upstream DTC tree:
commit 651410e54cb9 ("util: introduce xstrndup helper")
commit ec7986e682cf ("dtc: introduce label relative path references")
