Transceiver52M: Fix ARM build issues
Patch f147b174 "sigproc: Make convolution and convert input buffers
immutable" changed the internal conversion interface with the addition
of the const type qualifier. This change was not reflected on ARM builds
which led to build failure. Add const qualifier to resolve build issue.
