[PATCH net v3] net: stmmac: Fix ethool link settings ops for integrated PCS

[Sneh Shah]

Currently get/set_link_ksettings ethtool ops are dependent on PCS.
When PCS is integrated, it will not have separate link config.
Bypass configuring and checking PCS for integrated PCS.

Fixes: aa571b6275fb ("net: stmmac: add new switch to struct plat_stmmacenet_data")
Tested-by: Andrew Halaney <ahalaney@redhat.com> # sa8775p-ride
Signed-off-by: Sneh Shah <quic_snehshah@quicinc.com>
