Alexey Brodkin 92a190aaab net/designware - switch driver to phylib usage
With this change driver will benefit from existing phylib and thus
custom phy functionality implemented in the driver will go away:
 * Instantiation of the driver is now much shorter - 2 parameters
instead of 4.
 * Simplified phy management/functoinality in driver is replaced with
rich functionality of phylib.
 * Support of custom phy initialization is now done with existing
"board_phy_config".

Note that after this change some previously used config options
(driver-specific PHY configuration) will be obsolete and they are simply
substituted with similar options of phylib.

For example:
 * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
by default.
 * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
automatically the first discovered on MDIO bus phy will be used

I believe there's no need now in "doc/README.designware_eth" because
user only needs to instantiate the driver with "designware_initialize"
whose prototype exists in "include/netdev.h".
