Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
