[OpenPower-Firmware] Infiniband network boot kernel config additions

[Daniel M. Weeks]

Below are the kernel config additions I used to add mlx5, ipoib, and
userspace support to netboot via Infiniband. I'm not sure what the best
method is to add these options.

I expect the selection to be somewhat platform dependent but the kernel
configs are not as fine-grained as the platform configs. (Where the
userspace components can be added per-platform.)

CONFIG_INFINIBAND=m
CONFIG_MLX5_INFINIBAND=m
CONFIG_INFINIBAND_IPOIB=m
CONFIG_INFINIBAND_IPOIB_DEBUG=y
CONFIG_INFINIBAND_USER_ACCESS=m
