Define device-tree bindings for the tmio-mmc driver to be able to specify
parameters, currently provided in platform data.

Please, comment on this one, since it is defining an ABI

+* Toshiba Mobile IO SD/MMC controller
+
+The tmio-mmc driver doesn't probe its devices actively, instead its binding to
+devices is managed by either MFD drivers or by the sh_mobile_sdhi platform
+driver. Those drivers supply the tmio-mmc driver with platform data, that either
+describe hardware capabilities, known to them, or are obtained by them from
+their own platform data or from their DT information. In the latter case all
+compulsory and any optional properties, common to all SD/MMC drivers, as
+described in mmc.txt, should or can be used. Additionally the following optional
+bindings can be used. They set either respective TMIO_MMC_* flags or MMC_CAP_*
+capabilities.
+
+Optional properties:
+- toshiba,mmc-wrprotect-disable	: set TMIO_MMC_WRPROTECT_DISABLE flag
+- toshiba,mmc-blksz-2bytes	: set TMIO_MMC_BLKSZ_2BYTES
+- toshiba,mmc-cap-sdio-irq	: SDIO IRQ signalling should be used, if
+	supported by the hardware, i.e. set MMC_CAP_SDIO_IRQ if
+	TMIO_MMC_SDIO_IRQ is also set
+- toshiba,mmc-has-idle-wait	: set TMIO_MMC_HAS_IDLE_WAIT
