[PATCH] ppc32: Remove CONFIG_PMAC_PBOOK

This patch removes CONFIG_PMAC_PBOOK (PowerBook support).  This is now
split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
powerbooks have, CONFIG_PM for power management related code, and just left
out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.

-          This provides support for putting a PowerBook to sleep; it also
-          enables media bay support.  Power management works on the
-          PB2400/3400/3500, Wallstreet, Lombard, and Bronze PowerBook G3 and
-          the Titanium Powerbook G4, as well as the iBooks.  You should get
-          the power management daemon, pmud, to make it work and you must have
-          the /dev/pmu device (see the pmud README).
-
-          Get pmud from <ftp://ftp.samba.org/pub/ppclinux/pmud/>.

-          If you have a PowerBook, you should say Y here.
-
-          You may also want to compile the dma sound driver as a module and
-          have it autoloaded. The act of removing the module shuts down the
-          sound hardware for more power savings.
