[PATCH v2] powerpc: make Freescale QE support a selectable Kconfig option

[Timur Tabi]

Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable
option, thereby allowing users to compile kernels without any QE support.

The drawback is that QE support is now disabled by default on platforms that
have a QE, and so a defconfig is needed to enable QE and QE devices (like
UCC GETH).  Fortunately, all the current relevant defconfigs do that already.

This patch should be applied to Kumar's branch for 2.6.28 patches.

I have a few other patches that I've sent you over the past couple weeks that
you haven't applied:

powerpc: fix conflict with Elo DMA driver in MPC8610 device tree
powerpc: remove CHRP and PMAC support from defconfigs, fix Kconfigs
powerpc: remove support for bootmem-allocated memory for the DIU driver

For BenH to look at.
