net: phy: as21xxx: force C45 OPs for AUTONEG

With further testing with 2.5G NIC, it was discovered that the PHY
require the C45 OPs to configure and restart ANEG or speed higher than
1G doesn't function correctly.

To force C45 OPs with generic PHY function, clear the C22 bit from
devices_in_package bitmask.
