This feature allows to use SDIO bus without wiring card detect
signal. This is relevant in cases where SDIO device is connected to
SDIO bus and there is no way to disconnect device from bus (device
is always present).

The problem can be easily reproduced using a script that loops
copying a file in an SD card to another place in the same SD card
and its related to read transfers. This only happens with DMA enabled.
This is related to the fact that, when reading, an MMC irq signals
the fact that all data from the
Samsung Exynos SoC's extend the dw-mshc controller for additional clock and bus
control. Add support for these extensions and include provide device tree based
discovery suppory as well.

The core dw-mshc controller driver can let platform specific implementations
of the dw-mshc controller to control the hardware as required by such
implementations. This is acheived by invoking implementation specific (optional)
callbacks. Define the list of callbacks supported the add invocation po
Some platforms allow for clock gating and control of bus interface unit clock
and card interface unit clock. Add support for clock lookup of optional biu
and ciu clocks for clock gating and clock speed determination.
