Subject: [PATCH] fbdev/ps3fb: Build without kernel device

Use fb_info() to print status message at the end of the probe function,
which avoids decoding the devices. fb_info() works with or without an
fbdev kernel device. Fixes the following error:

../drivers/video/fbdev/ps3fb.c: In function 'ps3fb_probe':
