hw/vexpress: Pass proc_id via VEDBoardInfo
Pass the daughterboard-specific proc_id property to the code that creates the sysctl device via the VEDBoardInfo struct, rather than by having the daughterboard init function write to a uint32_t* argument. This is a cleaner way to pass the info around, and is in line with the way we are going to handle voltage and oscillator initialization. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
