net/ice: Add support for enable_iwarp and enable_roce devlink param
Allow support for 'enable_iwarp' and 'enable_roce' devlink params to turn
on/off iWARP or RoCE protocol support for E800 devices.
For example, a user can turn on iWARP functionality with,
devlink dev param set pci/0000:07:00.0 name enable_iwarp value true cmode runtime
This add an iWARP auxiliary rdma device, ice.iwarp.<>, under this PF.
A user request to enable both iWARP and RoCE under the same PF is rejected
since this device does not support both protocols simultaneously on the
same port.
