commit 6e2d85ec05591b739059f65fe8438c9c5999f7d8 upstream.
While consolidating the PHY reset in phy_init_hw() an unconditionaly BMCR soft-reset I became quite trigger happy with those. This was later on deactivated for the Generic PHY driver on the premise that a prior software entity (e.g: bootloader) might have applied workarounds in commit 0878fff1f42c ("net: phy: Do not perform software reset for Generic PHY").
Since we have a hook to wire-up a soft_reset callback, just use that and get rid of the call to genphy_soft_reset() entirely. This speeds up initialization and link establishment for most PHYs out there that do not require a reset.
