boards: sabre-6quad: The iperf works with CONFIG_NET_TCP_WRITE_BUFFERS

Browse Source 
Summary:
- This commit makes the iperf work with CONFIG_NET_TCP_WRITE_BUFFERS
- Since the iperf sends a large packet (e.g. 16KB), CONFIG_IOB_NBUFFERS
  must be increased enough to hold the packet
- To improve performance CONFIG_IMX_ENET_NTXBUFFERS was changed to
  the default (i.e. 2)

Impact:
- sabre-6quad:netnsh only

Testing:
- Tested with iperf with QEMU
