The PL061 comes out of reset with all its lines configured as input, which means they might need to be pulled to 0 or 1 depending on the 'pullups' and 'pulldowns' properties. Currently we do not assert these lines on reset; they will only be set whenever the guest first touches a register that triggers a call to pl061_update(). Convert the device to three-phase reset so we have a place where we can safely call qemu_set_irq() to set the floating lines to their correct values.
