ARM: Add support for EDB93XX boards [rev2]

Second revision of the patch set for EDB93XX boards

---
Changes:
* have different patches for CPU, network driver and boards
* reimplemented most of assembly code in C
* use structures for register maps instead of constants
* use MACH_TYPE instead of hard coded values
* set CONFIG_SYS_HZ to 1000 and rework timer code
* use get_ram_size() instead of relying on constants
* ported ethernet driver to CONFIG_NET_MULTI
* use common debug macros in ethernet driver and added macro ERROR to common.h
* eliminate use of bit fields in ethernet driver
* move declarations of ethernet driver to header file
* moved ethernet driver to drivers/net
* fixed coding style issues
* combine declaration of get_XCLK() functions with those of CONFIG_S3CXXXX
* removed scripting from Makefile
* added missing boards to Makefile
* keep board list in Makefile sorted
* added myself as maintainer for edb9xxx boards
* added edb93xx boards to MAKEALL
* simplified board config file
* removed board specific network settings
* removed unused functions
