/**
* Check if a dt node should be or was bound before relocation.
*
* Devicetree nodes can be marked as needed to be bound
* in the loader stages via special devicetree properties.
*
* Before relocation this function can be used to check if nodes
* are required in either SPL or TPL stages.
*
* After relocation and jumping into the real U-Boot binary
* it is possible to determine if a node was bound in one of
* SPL/TPL stages.
*
* There are 3 settings currently in use
* -
* - u-boot,dm-pre-reloc: legacy and indicates any of TPL or SPL
* Existing platforms only use it to indicate nodes needee in
* SPL. Should probably be replaced by u-boot,dm-spl for
* existing platforms.
* @blob: devicetree
* @offset: node offset
*
* Returns true if node is needed in SPL/TL, false otherwise.
