[ALSA] sound/ppc/pmac.c typo

Modules: PPC PMAC driver

In 2.6.16-rc1 there is a small typo introduced by the
'Remove device_node addrs/n_addr' changes
which prevents my Powerbook G4 sound from working:

	Advanced Linux Sound Architecture Driver Version 1.0.11rc2
	(Wed Jan 04 08:57:20 2006 UTC).
	snd: can't request rsrc  0 (Sound Control: 0x80000000:80004fff)
	ALSA device list:
	   No soundcards found.

The patch below fixes it. Of course, the patch fixing the i2c issues
('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in
order for the sound to completly work.
