The ppc4xx architecture was removed, and with it several old gdsys 44x

Some DM drivers have hardcoded clk_enable calls when handling

To support OF_EMBED, the MPC83xx architecture has to define the "_end"
symbol to correctly access the appended DT.

Fortunately, MPC8xx already defines the symbol, and the linker script is
quite similar to that of MPC83xx, so copy this approach for MPC83xx.

Lots of stuff in processor.h was taken verbatim from the Linux kernel.
It was never synced, so most of it was removed or changed in the kernel
since it was imported.

Remove all the stuff that is unused in the current U-Boot sources;
should anybody feel the need to re-sync with the kernel, they can do it
later on.

For a lot of inline assembly calls in the mpc8xxx and mpc83xx

ppcDWstore/ppcDWload are hardly used by any board, but since they're

compiler can decide when to actually include them.

Except for one counter example, CONFIG_SYS_LBC_LBCR always has a value
of either 0x00040000 or 0x00000000.

CONFIG_SYS_LBC_MRTPR always has the value 0x20000000.

CONFIG_SYS_LBC_LSDMR_{1,2,4,5} are not set for any mpc83xx board.

CONFIG_SYS_LBC_LSRT is set by one board (to 0x32000000).
