A few PHY drivers have the GPLv2 license text. They then either have
a MODULE_LICENSE() of GPLv2+, or an SPDX tag of GPLv2+.
Since the license text is much easier to understand than either the
SPDX tag or the MODULE_LICENSE, use it as the definitive source of the
licence, and fixup with others when there are contradictions.

Now that flag PHY_HAS_INTERRUPT has been replaced with a check for
callbacks config_intr and ack_interrupt, we can remove setting this
flag from all driver configs.
Last but not least remove flag PHY_HAS_INTERRUPT completely.

DP83620 register set is compatible with the DP83848, but it also supports
100base-FX. When the hardware is configured such as that fiber mode is
enabled, autonegotiation is not possible.
The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE.
Instead, this bit is always set high, even if the particular hardware
configuration makes it so that auto negotiation is not possible [1]. Under
these circumstances, the phy subsystem keeps trying for autonegotiation to
happen, without success.
Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on
reset is set to 0 when auto negotiation is disabled, and so we use this
value instead of BMSR_ANEGCAPABLE.

Add support for the TI DP83822 10/100Mbit ethernet phy.
The DP83822 provides flexibility to connect to a MAC through a
standard MII, RMII or RGMII interface.
In addition the DP83822 needs to be removed from the DP83848 driver
as the WoL support is added here for this device.
