powerpc, 8xx: remove support for 8xx
There was for long time no activity in the 8xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8xx,
so remove it (with a heavy heart, knowing that I remove
here the root of U-Boot).

-/* U-Boot - Startup Code for PowerPC based Embedded Boards
- *
- *
- * The processor starts at 0x00000100 and the code is executed
- * from flash. The code is organized to be at an other address
- * in memory, but as long we don't jump around before relocating,
- * board_init lies at a quite high address and when the cpu has
- * jumped there, everything is ok.
- * This works because the cpu gives the FLASH (CS0) the whole
- * address space at startup, and board_init lies as a echo of
- * the flash somewhere up there in the memory map.
- *
- * board_init will change CS0 to be positioned at the correct
- * address and (s)dram will be positioned at address 0
