[voq/inband]Inband port name change

Signed-off-by: vedganes <vedavinayagam.ganesan@nokia.com>

Based on review comments Recyle port HLD
(sonic-net/SONiC#742) the inband port name prefix is
changed from Inband to "Ethernet-IB" similar to what we have for
Ethernet-BP (Ethernet-Backplane) in multi-asic design. Because of this
changes, we no longer need "INBAND_PREFIX" definition since Ethernet-IB
is covered in "INTFS_PREIFX"
