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.
