ASoC: fsi: fixup SND_SOC_DAIFMT_CBx_CFx flags

SND_SOC_DAIFMT_CBx_CFx means "codec" side master/slave mode.
Then, FSI will be master mode if it was SND_SOC_DAIFMT_CBS_CFS.

This patch fixup platform settings too.
Then, it tidyups SND_SOC_DAIFMT_INV settings.

Revert "ARM: shmobile: marzen: Conditionally select SMSC_PHY"

This reverts commit 317af6612ee29dfcb5ae04df9c58e9f79fc8d4ff.

This seems to prevent the board from booting now that the tree has been
rebased on v3.14-rc1.

ARM: shmobile: Lager USB0 cable detection workaround

Add Lager board code to check the PWEN GPIO signal and refuse to
allow probe of the USBHS driver in case of DIP misconfiguration.

For correct operation Lager DIP switches SW5 and SW6 shall be
configured in 2-3 position to enable USB Function support.

If the DIP switch is configured incorrectly then the user can
simply adjust the hardware and either reboot or use the bind interface
to try to probe again:

Remove ifdefs to make the Lager USBHS device always present.
This makes it more like other devices, no need to be special.

Also, these ifdefs by themselves do not hurt much, but combined
with USB Host device ifdefs that were proposed earlier we could
basically end up with a kernel that drives VBUS incorrectly
