Arm Vexpress updates for v6.11

Remove obsolete RTSM DCSCB support which was only ever implemented
on a software model which is neither available to download nor
maintained. It predates the very first bL cluster based platforms.

Other change include addition of the missing MODULE_DESCRIPTION
macro in vexpress config bus driver.
