QMC driver take #1

Hi

This is a patch that enables the use of
the QMC multichannel controller which exists in the Motorola 8xx processors.

It applied to a vanilla 2.4.20 kernel, but should apply to any 2.4 kernel.

The patch itself is divided in 3 parts.

#1 - The export of invalidate_dcache_range

It enables to build the driver as a module.

This patch is *NOT* needed for the linuxppc-2.4 tree, where it is exported by default.

#2 - The QMC hw definitions

These are the hardware definitions required by the
driver.

#3 - The QMC driver itself.

This driver by itself does nothing.
It exports an interface which other drivers can use in order to do something useful.

The netvia_bri2 is an actual driver, for my custom hardware which implements a BRI interface.

Don't try to build it since other parts are missing.

More documentation shall be forthcoming by Monday.

Enjoy.
