ARM: shmobile: r8a7790: add audio clock
Current audio clock doesn't have dependency to device/driver, but, it is not good design for DT support. To avoid branch merge conflict issue, it uses this load map, and this patch is 1) part. 1) add old/new style clock in platform 2) add new style clock method in driver 3) remove old tyle clock from platform Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
