[PATCH] ADB stuffs (req. for trackpad patch)

[Benjamin Herrenschmidt]

Enclosed is a patch to drivers/macintosh/adb.c (and
includes/asm-ppc/adb.h since there's a new exported function).

The new function handles ADB handlerID negociation (try to change the
default handler ID of a device, returns if it fails). It updates the
kernel's internal table of handlerIDs too, just in case...

It's called by new hardware init code in the previously sent patch to
mac_keyb.c

Note also that I changed the adb register function so that it matches by
handlerID or original address. if you want to match by original address,
pass 0 to handlerID, if you want the opposite, pass 0 to original address.
