net: hsr: Create and export hsr_get_port_ndev()
Create an API to get the net_device to the slave port of HSR device. The
API will take hsr net_device and enum hsr_port_type for which we want the
net_device as arguments.
This API can be used by client drivers who support HSR and want to get
the net_devcie of slave ports from the hsr device. Export this API for
the same.
This API needs the enum hsr_port_type to be accessible by the drivers using
hsr. Move the enum hsr_port_type from net/hsr/hsr_main.h to
include/linux/if_hsr.h for the same.
