Subject: [PATCH v3 06/25] ARM: Prepare Actions Semi S500

Add ARCH_ACTIONS and mach-actions/owl.c for "actions,s500".

Signed-off-by: Andreas Färber <afaerber@...e.de>
---
 v2 -> v3:
 * Selected AMBA, global timer, TWD drivers
 * Fixed copy&paste in machine definition (Alberto)
 
 v1 -> v2:
 * Renamed ARCH_OWL to ARCH_ACTION (Arnd)
 * Renamed mach-owl to mach-actions, leaving owl.c
 * Adopted "actions" vendor prefix
 * Selected new clocksource driver
