Take the WoWLAN handling code out of the main suspend function,
dividing it into three parts: get_config (which is used before the
firmware is switched), switch_to_d3 (which handles the rebooting of
the hardware with the D3 firmware) and config (which configures the D3
firmware for WoWLAN operation). This is necessary to prepare for the
net-detect implementation, which will use only the switch_to_d3 part
of this flow.

The "goto chip_reset" is a bit misleading, because it does not actually
issue a chip reset. Instead it is bypassing processing of other
interrupts and assumes that the tasklet will issue a chip reset.
In the case of RXORN this does not happen, so bypassing processing of
other interrupts will simply allow them to fire again. Even if RXORN
was triggering a reset, it is not critical enough to need the bypass
here.
