net: Kconfig:make PHY_GIGE and individual Micrel PHYs selectable
This change migrate the following configuration options for Kconfig:
* PHY_GIGE, indicates that a controller (with an appropriate PHY) is
Gigabit capable and enables extra support in the miiutil for
parsing the status of Gigabit PHYs
* adds configuration options for Micrel KSZ9021 and KSZ9031 GbE PHYs,
which previously had to enabled through a board-specific config file
