Subject: [PATCH] ps3: Introduce CONFIG_PS3_ADVANCED

ps3: Introduce CONFIG_PS3_ADVANCED, as suggested by Roman Zippel, and use it to
control questions about PS3 subsystems that may not be obvious for the casual
user.

This gets rid of the following warning on non-powerpc platforms:
| drivers/video/Kconfig:1604:warning: 'select' used by config symbol 'FB_PS3' refer to undefined symbol 'PS3_PS3AV'
