powerpc: Remove arch/ppc and include/asm-ppc
All the maintained platforms are now in arch/powerpc, so the old arch/ppc stuff can now go away.

*
|

* In addition to the individual control of the communication
|
||||
* channels, there are a few functions that globally affect the
|
||||
* communication processor.
|
||||
*
|
||||
* Buffer descriptors must be allocated from the dual ported memory
|
||||
* space. The allocator for that is here. When the communication
|
||||
* process is reset, we reclaim the memory available. There is
|
||||
* currently no deallocator for this memory.
|
||||
* The amount of space available is platform dependent. On the
|
||||
* MBX, the EPPC software loads additional microcode into the
|
||||
* communication processor, and uses some of the DP ram for this
|
||||
* purpose. Current, the first 512 bytes and the last 256 bytes of
|
||||
* memory are used. Right now I am conservative and only use the
|
||||
* memory that can never be used for microcode. If there are
|
||||
* applications that require more DP ram, we can expand the boundaries
|
||||
* but then we have to be careful of any downloaded microcode.
