ARM: dts: Fix exynos5250-snow's search key to be L_META

The device tree sent upstream for exynos5250-snow encoded the search
key as CAPSLK.  However in all ChromeOS kernels it is L_META.  One can
certainly have long debates about which it ought to be, but I'm
proposing setting it to L_META because:
* That's how _all_ ChromeOS kernels do it and will do it.
* There is no L_META key on the board, so it's nice to have.
* For those people who really want it to be caps lock, they can use
  xmodmap or somesuch.

ARM: dts: change status property of dwmmc nodes for exynos5250

According to ePAPR, chapter 2.3.4, the status property has
defined that it should be set to "disabled" when "the device
is not presently operational, but it might become operational
in the future".

dts file and enable dwmmc node by "status = okay" in board specific
dts file.

clk: tegra: implement a reset driver

The Tegra CAR module implements both a clock and reset controller. So
far, the driver exposes the clock feature via the common clock API and
the reset feature using a custom API. This patch adds an implementation
of the common reset framework API (include/linux/reset*.h). The legacy
reset implementation will be removed once all drivers have been
converted.
