Subject: [PATCH net] net: hns: fix LED configuration for marvell phy

Since commit(net: phy: marvell: change default m88e1510 LED configuration),
the active LED of Hip07 devices is always off, because Hip07 just
use 2 LEDs.
This patch adds a phy_register_fixup_for_uid() for m88e1510 to
correct the LED configuration.

Fixes: 077772468ec1 ("net: phy: marvell: change default m88e1510 LED configuration")
