net: phy: Fixup GPLv2 SPDX tags based on license text

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.
