GPY115 need reset PHY when it comes out from loopback mode if the firmware
version number (lower 8 bits) is equal to or below 0x76.
Fixes: 7d901a1e878a ("net: phy: add Maxlinear GPY115/21x/24x driver")
Signed-off-by: Xu Liang <lxu@maxlinear.com>

v2 changes:
Remove wrong comment.
Use genphy_soft_reset instead of modifying MII_BMCR register to trigger PHY reset.
