Adding APM X-Gene SoC Ethernet driver.

v7: Address comments from v6 review
* fixed skb memory leak when dma_map_single fails in xmit.

v6: Address comments from v5 review
* added basic ethtool support
* added ndo_get_stats64 call back
* deleted priting Rx error messages
* renamed set_bits to xgene_set_bits to fix kbuild error (make ARCH=powerpc)

v5: Address comments from v4 review
* Documentation: Added phy-handle, reg-names and changed mdio part
* dtb: Added reg-names supplemental property
* changed platform_get_resource to platform_get_resource_byname
* added separate tx/rx set_desc/get_desc functions to do raw_write/raw_read
* removed set_desc/get_desc table lookup logic
* added error handling logic based on per packet descriptor bits
* added software managed Rx packet and error counters
* added busy wait for register read/writes
* changed mdio_bus->id to avoid conflict
* fixed mdio_bus leak in case of mdio_config error
* changed phy reg hard coded value to MII_BMSR
* changed phy addr hard coded value to phy_device->addr
* added paranthesis around macro arguments
* converted helper macros to inline functions
* changed use of goto's only to common work such as cleanup

v4: Address comments from v3 review
* MAINTAINERS: changed status to supported
* Kconfig: made default to no
* changed to bool data type wherever applicable
* cleaned up single bit set and masking code
* removed statistics counters masking
* removed unnecessary OOM message printing
* fixed dma_map_single and dma_unmap_single size parameter
* changed set bits macro body using new set_bits function

v3: Address comments from v2 review
* cleaned up set_desc and get_desc functions
* added dtb mdio node and phy-handle subnode
* renamed dtb phy-mode to phy-connection-type
* added of_phy_connect call to connec to PHY
* added empty line after last local variable declaration
* removed type casting when not required
* removed inline keyword from source files
* removed CONFIG_CPU_BIG_ENDIAN ifdef

v2
* Completely redesigned ethernet driver
* Added support to work with big endian kernel
* Renamed dtb phyid entry to phy_addr
* Changed dtb local-mac-address entry to byte string format
* Renamed dtb eth8clk entry to menetclk

v1
* Initial version
