[POWERPC] 8xx: Remove unused m8xx_cpm_hostalloc/free/dump()
m8xx_cpm_hostalloc is still defined in commproc.c, but no users are left in the kernel tree. m8xx_cpm_hostfree and m8xx_cpm_hostdump are only defined in the headers. Remove this dead code. Signed-off-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
