mmc: add DT bindings for more MMC capability flags
Many MMC capability flags are platform-dependent and are traditionally set in platform data. With DT often each such capability requires a special binding. Add bindings for MMC_CAP_SD_HIGHSPEED, MMC_CAP_MMC_HIGHSPEED, MMC_CAP_POWER_OFF_CARD and MMC_CAP_SDIO_IRQ capabilities. Also add code to DT parser to look up "keep-power-in-suspend" and "enable-sdio-wakeup" bindings and set MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ respectively, if found.
