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.

mmc: tegra: assume CONFIG_OF, remove platform data

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Rework the driver to parse the device tree
directly into struct sdhci_tegra.

asus-wmi: update wlan LED through rfkill led trigger

For those machines with wapf=4, BIOS won't update the wireless LED,
since wapf=4 means user application will take in chage of the wifi and bt.
So, we have to update wlan LED status explicitly.

But I found there is another wireless LED bug in launchpad and which is
not in the wapf=4 quirk.
So, it might be better to set wireless LED status explicitly for all
machines.

msi-laptop: Disable brightness control for new EC

It seems that existing brightness control works only for old EC models.
On newer ones auto_brightness access always timeouts and lcd_level
always shows 0. So disable brightness control for new EC models. It
works fine with ACPI video driver anyway.
