This means that davinci_cpdma.o can be linked to a module and also to vmlinux even though the expected CFLAGS are different between builtins and modules. This is the same situation as fixed by commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects"). Introduce the new module, ti_davinci_cpdma, to provide the common functions to these three modules.
