[patch 61/71] powerpc/ps3: Add missing check for PS3 to rtc-ps3 platform device registration

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Geert Uytterhoeven <Geert.Uytterhoeven@xxxxxxxxxxx>

commit 7b6a09f3d6aedeaac923824af2a5df30300b56e9 upstream.

On non-PS3, we get:

| kernel BUG at drivers/rtc/rtc-ps3.c:36!

because the rtc-ps3 platform device is registered unconditionally in a kernel
with builtin support for PS3.
