[PATCH V3 2/3] net: phy: Drop phy_interface_is_sgmii

[Nishanth Menon]

Recent commit 75d28899e3e9 ("net: phy: Synchronize PHY interface modes
with Linux") reordered the enum definitions. This caused the range of
enums that this api was checking to go bad.

There aren't anymore users of phy_interface_is_sgmii, so, just drop
it. Also the protocols are so very different that it makes no sense to
provide a helper wrapper in the hope of reuse for phy drivers.
