Subject: net: phy: bcm7xxx: define soft_reset for 40nm EPHY
Patch-mainline: v5.4-rc4
Git-commit: fe586b823372a9f43f90e2c6aa0573992ce7ccb7
References: bsc#1119113 FATE#326472

The internal 40nm EPHYs use a "Workaround for putting the PHY in
IDDQ mode." These PHYs require a soft reset to restore functionality
after they are powered back up.

This commit defines the soft_reset function to use genphy_soft_reset
during phy_init_hw to accommodate this.

Fixes: 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
