simonJi2018 49f3b22de5 [device] various improvement for nephos devices (#3139)
Add fan control for as7116-54x
Modify sfputil.py to support sfp insert and remove events for as7116-54x
Modify port_config.nps to set port default admin down
Modify port_config.ini for add speed attr
Code format optimization like remove newline
Modify buffers_defaults_t0 and t1, change ingress_lossless_pool mode from dynamic to static
Add nephos_dac.nps and nephos_opt.nps for support difference dac and fiber module
