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