Subject: [PATCH net-next v4 2/2] net: fec: Refactor: Replace FEC_ENET_FCE with FEC_RCR_FLOWCTL

FEC_ENET_FCE is the Flow Control Enable bit (bit 5) of the RCR.
This is now defined as FEC_RCR_FLOWCTL.

Notes:
    Changes in v4:
    * factored out the removal of FEC_ENET_FCE
    
    Changes in v3:
    * remove `u32 ecntl` from `fec_stop()`
    * found another ETHEREN in `fec_restart()`
