ice: add 40G speed to Admin Command GET PORT OPTION
Introduce the ICE_AQC_PORT_OPT_MAX_LANE_40G constant and update the code
to process this new option in both the devlink and the Admin Queue Command
GET PORT OPTION (opcode 0x06EA) message, similar to existing constants like
ICE_AQC_PORT_OPT_MAX_LANE_50G, ICE_AQC_PORT_OPT_MAX_LANE_100G, and so on.
This feature allows the driver to correctly report configuration options
for 2x40G on E823 and other cards in the future via devlink.
Example command:
devlink port split pci/0000:01:00.0/0 count 2
Example dmesg:
ice 0000:01:00.0: Available port split options and max port speeds (Gbps):
ice 0000:01:00.0: Status Split Quad 0 Quad 1
ice 0000:01:00.0: count L0 L1 L2 L3 L4 L5 L6 L7
