ASoC: renesas: fsi: Constify struct fsi_stream_handler

Browse source

'struct fsi_stream_handler' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:
