hw/gpio/pl061: Convert to 3-phase reset and assert GPIO lines correctly on reset

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.
