powerpc/8xx: move CPM1 related files from sysdev/ to platforms/8xx
Only 8xx selects CPM1 and related CONFIG options are already in platforms/8xx/Kconfig Move the related C files to platforms/8xx/. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> [mpe: Minor formatting fixes] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

- * Copyright (c) 1997 Dan error_act (dmalek@jlc.net)
- *
- * 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.
