[PATCH] i2c: powermac: don't workaround for keywest

[Wolfram Sang <wsa@the-dreams.de>]

Commit 3a3dd0186f619b ("i2c/powermac: Improve detection of devices from
device-tree") added a codec device instantiation workaround
unconditionally although it is only needed for onyx. Do it conditionally
since keywest has its own codec instantiation in the sound drivers.
Thanks must go to GrowlTiger from Gentoo bug report #469132 for
bisecting.
