[PATCH] ppc32: Artesyn Katana platform update

- Adds MTD support for the soldered FLASH
- Adds cmdline parsing
- Turns on the Blue LED when the system is halted
- Moves some of the device window left by the firmware to proper alignments
- Handles possibility of different frequencies for TCLK & SysCLK in 64460
- Misc. code clean up
