Unlike the boot signature that needs to be set before every reset, the
ape state only needs to be updated to tell the firmware that the driver
is now taking/releasing control of the hardware. Move the calls to
tg3_ape_driver_state_change() to better, more appropriate places.

Also, the firmware does not distinguish between SUSPEND and START states
anymore. Remove the SUSPEND case in the switch.
