[PATCH 28/56] ASoC: core: Always send the CPU DAI a direct clock specifier

All CPU drivers are now updated to accept a direct indication of
whether they are clock provider or consumer, rather than being told
if the CODEC is clock provider. As such update the core to always
pass this direct indication rather than only if the new set_fmt_new
callback is defined. Note this makes no difference to the CODEC
side of the DAI link as it was already being directly told if it
was clock provider under the old system.
