[PATCH] powerpc: Fix machine detection in prom_init.c
In e8222502ee6157e2713da9e0792c21f4ad458d50 the detection of machine types in prom_init broke for some machines. We should be checking /device_type instead of /model. This should make Power3 and Power4 boot again. Haven't been able to test this. We also need to relocate before comparing.
