hw/phb4: Drop FRESET_DEASSERT_DELAY state
The delay between the ASSERT_DELAY and DEASSERT_DELAY states is set to
one timebase tick. This state seems to have been a hold over from PHB3
where it was used to add a 1s delay between de-asserting PERST and
polling the link for the CAPI FPGA. There's no requirement for that here
since the link polling on PHB4 is a bit smarter so we should be fine.
