of: Compare property names by of_prop_cmp() in of_alias_scan()

For these pseudo property names 'name', 'phandle' and 'linux,phandle':

Use dedicated property name comparison macro of_prop_cmp() instead of
strcmp() in of_alias_scan() to:

- Make property name comparison consistent.
- Prepare for introducing private is_pseudo_property() later.
