By default, the device tree compiler emits phandle properties twice:
one called 'phandle' and another called 'linux,phandle'. Given that
Linux was updated in early 2010 [0] to accept the former (which is
what is specified in the ePAPR and device tree specifications), there
is no point in emitting both when compiling device trees for UEFI
platforms.
