This patch updates the board specific USB support
code for the sh7372 Mackerel board.

With this patch applied port CN22 is driven by the
recently added renesas_usbhs driver using the first
USB controller included in sh7372 aka USBHS0.

Hotplugging of USBHS0 unfortunately has to be
handled by software polling. The sh7372 SoC itself
obviously supports hotplug notification by IRQ but
on the Mackerel board this IRQ happens to be used
for the touch screen.

Also fix the pinmux configuration to avoid setting
up unused pins and fix minor spelling errors.

On sh7372 the card-detection pin of SDHI0 can also produce interrupts,
when configured as GPIO. Use this feature to power down SDHI0, when no
card is plugged in.

renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.

mackerel board has 2 USB ports.

But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.

We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.

Add sh7372 Core Standby sleep mode support and tie it
in with the shared SH-Mobile ARM suspend code.

The Core Standby mode is the lightest sh7372-specific
sleep mode, cutting power to the ARM core excluding the
L2 cache. Any interrupt source can be used for wakeups.

The low level portion of this code is based on the
TI OMAP sleep code in sleep34xx.S, thanks to them.

This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and
supplies 3 IRQ resources for each SDHI block.

Some blocks have a 4th IRQ, but this is used for DRM feathres
that I do not have access tot he documentation for and are almost
certainly tainted by licensing issues. So the 4th IRQ is not
hooked-up even if it exists.

Current format selection of FSI-codecs depended on platform information for FSI,
and chip default settings for codecs. It is not understandable/formal method.
This patch modify FSI and FSI-codecs to use snd_soc_dai_set_fmt.

But FSI can use I2S/PCM and SPDIF format today.
It can be selected to I2S/PCM by snd_soc_dai_set_fmt, but can not select SPDIF.
So, this patch change FSI platform information to have DAI/SPDIF mode.

If platform selects DAI mode (default),
FSI-codecs can select I2S/PCM by snd_soc_dai_set_fmt,
and if it is SPDIF mode, FSI become SPDIF format.
