Renesas devices the build does not select it. This means that there
are configurations that do not allow the AHB-PCI bridge used for the

Add Koelsch and r8a7791 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Koelsch board support exists in 3 flavors:
1) SHMOBILE_MULTI, MACH_KOELSCH - board-koelsch-reference.c (CCF + DT)
2) SHMOBILE, MACH_KOELSCH_REFERENCE - board-koelsch-reference.c (DT)
3) SHMOBILE, MACH_KOELSCH - board-koelsch.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.

SH-Mobile platforms are transitioning from non-multiplatform to
multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has
been created to group all multiplatform-enabled SH-Mobile SoCs. The
existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't
been converted yet.

This arrangement works fine for the arch/ code, but lots of drivers
needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on
ARCH_SHMOBILE only. In order to avoid changing them, rename
ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean
ARCH_SHMOBILE configuration symbol that is selected by both
ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

This patch enables R-Car sound,

on Bock-W.

But, it supports PIO transfer only at this point.
User can check sound settings (Dip-switch/PFC etc)
via this patch, but will get under/over flow error
when playback/capture.
Because PIO transfer via SSI will be interrupted
"sampling rate" times per 1 second.

DMA transfer will be supported when HPB-DMAC was
enabled on r8a7778.

You will notice strange ALSA sound card HW
numbering on Bock-W board.
This came from AK4554 strange format on playback/capture.
The format on playback/capture is same on "normal" codec chip,
but AK4554 was different.
Because of that, AK4554 playback/capture are
registered as a different sound card.
