fdt: update fdt_alloc_phandle to use fdt_get_phandle
The device tree compiler, dtc, can use "phandle" and/or "linux,phandle"
properties to specify the phandle for any node. By default, it uses
both, but "linux,phandle" is deprecated. One day, we'd like to stop using
"linux,phandle", but U-boot needs to support both properties equally
first.
fdt_alloc_phandle() generates a unique phandle, but it was only checking
the "linux,phandle" properties. Instead, we use fdt_get_phandle(),
which checks both properties automatically. This ensures that we
support dtbs that only use "phandle".
The side-effect is that fdt_alloc_phandle() now takes twice as long, since
it has to check for two properties instead of one in each node that it
searches.
