Hello,

This patchset fixes reboot hang issue on Hardkernel's Odroid boards with
eMMC card. Those boards are designed in such a way, that the eMMC nreset
signal is routed to SoC GPIO line instead of the board reset logic. To
properly restard system, one need to set this line to zero before
performing reboot.

The initial patches consisted of a complete reset/power off driver, but
after further analysis, it turned out that only eMMC nreset line control
logic is specific for those boards. Everything else can be done by
generic Exynos code, so the code has been moved to Exynos DW MMC driver.
