[POWERPC] Updates/fixes to 32 bits pcibios_enable_device()
Our implementation of pcibios_enable_device() incorrectly ignores the mask argument and always checks that all resources have been allocated, which isn't the right thing to do anymore. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
