RDMA/nes: Add support for KR device id 0x0110

Browse Source 
Add support for KR device id 0x0110.  While at it, cleanup
nes_init_phy() by splitting it into nes_init_1g_phy() and
nes_init_2025_phy().

Remove support for NES_PHY_TYPE_IRIS, which was used on an XFP board
that was only manufactured in small quantities and given out for evals
in even smaller quantities.
