ARM: shmobile: use FSI driver's audio clock on mackerel
Current FSI driver can control audio clock without platform call-back functions This patch removed board-specific call-back/settings Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms@verge.net.au>hifive-unleashed-5.1
