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>
