net: phy: phy driver features are mandatory

Browse source

[ Upstream commit 3e64cf7a43 ]

Since phy driver features became a link_mode bitmap, phy drivers that
don't have a list of features configured will cause the kernel to crash
when probed.

Prevent the phy driver from registering if the features field is missing.
