As the old ethernet PHY is not available any more, the x600 board has
been redesigned with the Micrel KSZ9031 PHY. This patch adds support
to autodetect the PHY and configure the Micrel PHY correctly.

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 patch adds support for the X600 SPEAr600 based board. Its also
the first SPEAr600 board that uses the newly introduced SPEAr600
SPL support. Xloader is not necessary any more. By using the new
"u-boot.spr" make target, one image will generated containing both,
U-Boot SPL (with mkimage header as needed by the SPEAr BootROM, and
the main U-Boot with mkimage header.
