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".

-This driver supports Designware Ethernet Controller provided by Synopsis.
-
-The driver is enabled by CONFIG_DESIGNWARE_ETH.
-
-The driver has been developed and tested on SPEAr platforms. By default, the
-MDIO interface works at 100/Full. #defining the below options in board
-configuration file changes this behavior.
-
-Call an subroutine from respective board/.../board.c
-designware_initialize(u32 id, ulong base_addr, u32 phy_addr);
-
-The various options suported by the driver are
-1. CONFIG_DW_ALTDESCRIPTOR
- Define this to use the Alternate/Enhanced Descriptor configurations.
-1. CONFIG_DW_AUTONEG
- Define this to autonegotiate with the host before proceeding with mac
- level configuration. This obviates the definitions of CONFIG_DW_SPEED10M
- and CONFIG_DW_DUPLEXHALF.
-2. CONFIG_DW_SPEED10M
- Define this to change the default behavior from 100Mbps to 10Mbps.
-3. CONFIG_DW_DUPLEXHALF
- Define this to change the default behavior from Full Duplex to Half.
-4. CONFIG_DW_SEARCH_PHY
- Define this to search the phy address. This would overwrite the value
- passed as 3rd arg from designware_initialize routine.
