[POWERPC] Setup RTAS values earlier, to enable rtas_call() earlier
Althought RTAS is instantiated when we enter the kernel, we can't actually call into it until we know its entry point address. Currently we grab that in rtas_initialize(), however that's quite late in the boot sequence. To enable rtas_call() earlier, we can grab the RTAS entry etc. values while we're scanning the flattened device tree. There's existing code to retrieve the values from /chosen, however we don't store them there anymore, so remove that code.
