dm: remove pre reloc properties in SPL and TPL device tree

We can remove the pre reloc property in SPL and TPL device-tree:
- u-boot,dm-pre-reloc
- u-boot,dm-spl
- u-boot,dm-tpl
As only the needed node are kept by fdtgrep (1st pass).

The associated function (XXX_pre_reloc) are simple for SPL/TPL:
return always true.
