ARM: Add support for EDB93xx boards [rev4]

4th revision of the patch set for EDB93xx boards

---
Changes with respect to rev3:

general
* fixed coding style issues

arch
* added declaration of prototypes of get_XCLK()

ethernet driver
* renamed to ep93xx_eth
* removed unnecessary ifdef
* use a private structure for each instance instead of a global one
* get mac address from dev->enetaddr
* renamed init function to ep93xx_eth_initialize()
* pass base address and device number to ep93xx_eth_initialize()
* changed order of functions to avoid forward declarations
* removed packed attribute from structures of 32 bit integers
* removed declaration of prototypes of get_XCLK()

board
* use DECLARE_GLOBAL_DATA_PTR at file level
* renamed MACH_TYPE to CONFIG_MACH_TYPE
* use memcpy instead of copying the exception vectors manually
* added file header to board config file
