[PATCH 5.5 025/151] net: phy: bcm63xx: fix OOPS due to missing driver name

[Greg Kroah-Hartman]

From: Jonas Gorski <jonas.gorski@xxxxxxxxx>

[ Upstream commit 43de81b0601df7d7988d3f5617ee0987df65c883 ]

719655a14971 ("net: phy: Replace phy driver features u32 with link_mode
bitmap") was a bit over-eager and also removed the second phy driver's
name, resulting in a nasty OOPS on registration:

Fix it by readding the name.
