[HAL] remove HAL_PORT_RX_SETUP_STATE_CALIB_NO_LPDC from hal_port_fsm_rx and move bitslide measurement

Rational: when LPDC is done, we need to wait for link_up (the
early_link_up is already set). There can be potentially time
when we are in the HAL_PORT_RX_SETUP_STATE_DONE done state and
the early_link_up=1 while link_up=0. This forces a bit different
behavior for the LPDC and non-LPDC behavior. The new approarch:
- if no LPDC, go directly to HAL_PORT_RX_SETUP_STATE_DONE and
  wait there for link_up
- if LPDC, do the all the necessary stuff and then wait for
  link_up in HAL_PORT_RX_SETUP_STATE_DONE
The bitslide measurement could be done only for non-LPDC, yet
there is no harm in reading the bitslide register in all cases,
it is hardcoded to zero when LPDC is supported. Doing it
outside the hal_port_fsm_rx is more similar to what was in the
original HAL, furthermore, bitslide measurement was there before
LPDC, so it can be considered somehow independent
