[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'

+	help
+	  This gives you access to some advanced options for the PS3. The
+	  defaults should be fine for most users, but these options may make
+	  it possible to better control the kernel configuration if you know
+	  what you are doing.
+
+	  Note that the answer to this question won't directly affect the
+	  kernel: saying N will just cause the configurator to skip all
+	  the questions about these options.
+
+	  Most users should say N to this question.
