[PATCH] ppc32: Remove CONFIG_PMAC_PBOOK

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Hi !

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.

It applies on top of my two previous patches removing macserial and
fixing the PMU irq priority.

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
