cmemk: Fix 5.10 build errors for non Keystone2 platforms

The commit 8aba20e20bf7 ("cmemk: Fix build errors for 5.10+ kernels")
introduced a return type for cmem_dma_offset_configure(), but the
function is not returning a value for all code paths. This causes
a build failure for non Keystone 2 platforms. Fix this.
