[PATCH 2.6] set up conswitchp when CONFIG_VT is set

[Jun Sun <jsun@mvista.com>]

conswitchp needs to be set whenever CONFIG_VT is selected.
Currently this job is done individually by each board in its setup
routine, often in a wrong way.

The right thing to do is to set the pointer in the common code
and remove almost two dozens of duplicated and often wrong settings.

The attached patch is for illustration only.  The removal of board settings
is not complete.

Comments?  Objections and cheers are equally welcome. :)
