[PATCH] Fix build break caused by "ide: remove ideprobe_init()"

[Olof Johansson]

Fix build break of powerpc holly_defconfig:

In file included from arch/powerpc/platforms/embedded6xx/holly.c:24:
include/linux/ide.h:1206: error: 'CONFIG_IDE_MAX_HWIFS' undeclared here (not in a function)

There's no need to have a sized array in the prototype, might as well
turn it into a pointer.

It could probably be argued that large parts of the include file can be
covered under #ifdef CONFIG_IDE, but that's a larger undertaking.

This patch broke builds of powerpc holly_defconfig in -mm. It has
CONFIG_EMBEDDED=y, CONFIG_IDE=n but includes linux/ide.h:
