net: hsr/prp: introduce net device lre ops for config and stats

LRE device requires configuration from user space through snmpd. This
patch introduces lredev ops in net_device struct to allow configure lre
parameters (attributes), query lre stats and node table from lower slave
devices when the lre is offloaded. This API is similar to the switch
device ops and is implemented in a similar manner.
