ARM: vexpress: Remove motherboard dependencies in the DTS files
The way the VE motherboard Device Trees were constructed enforced naming and structure of daughterboard files. This patch makes it possible to simply include the motherboard description anywhere in the main Device Tree and retires the "arm,v2m-timer" alias - any of the motherboard SP804 timers will be used instead. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
