[POWERPC] 8xx: Infrastructure code cleanup.

1. Keep a global mpc8xx_immr mapping, rather than constantly
creating temporary mappings.
2. Look for new fsl,cpm1 and fsl,cpm1-pic names.
3. Always reset the CPM when not using the udbg console;
this is required in case the firmware initialized a device
that is incompatible with one that the kernel is about to
use.
4. Remove some superfluous casts and header includes.
5. Change a usage of IMAP_ADDR to get_immrbase().
6. Use phys_addr_t, not uint, for dpram_pbase.
7. Various sparse-related fixes, such as __iomem annotations.
8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything
useful beyond the generic cpuinfo handler.
9. Move prototypes for 8xx support functions from board files
to sysdev/commproc.h.
