ARM: dts: Disable the RTC by default on exynos5

This change makes the rtc on the exynos5250 and 5440 disabled by
default to match exynos4.

Ever since the common clock framework came in, exynos5250 boards
have dumped lots of warnings in the boot log. It turns out that
we don't see those on exynos4 since the rtc is disabled by default.
While we need to get to the bottom of the problems with the RTC,
it still makes sense to have the default state of the RTC on exynos
boards match.

For the record, warnings look like this:

clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3}

commit 688f7d8c9fef ("clk: exynos5250: Fix divider values for
sclk_mmc{0,1,2,3}") incorrectly sets the divider for sclk_mmc{0,1,2,3}
to fix the wrong clock value. Though this fixed issue with Arndale,
it created regressions for other boards like Snow.

On Exynos5250, sclk_mmc<n> is generated like below (as per the clock
names in drivers/clk/samsung/clk-exynos5250.c)

mout_group1_p ==> mout_mmc<n> ==>
div_mmc<n> ==> div_mmc_pre<n> => sclk_mmc<n>

Earlier div_mmc<n> was set as the parent for sclk_mmc<n>, hence
div_mmc_pre<n> was not getting referred in kernel code and depending
on its value set during preboot, sclk_mmc<n> value was different for
various boards.

Setting the correct clock generation path should fix the issues
reported in above referenced commit. The changes committed during the
earlier patch has also been reverted here.

multiplatform kernel, in addition to keeping the single-platform
exynos support.

The multiplatform variant has a number of limitations at the moment:

* It only supports DT-enabled machines. This is not a problem in
  the long run, as non-DT machines for exynos are going away.
  The main problem here is that the gpio code and the exynos_eint
  irqchip are not multiplatform capable but still required for
  ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
  multiplatform.

The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

This branch contains most fixes and enhancements to the Tegra common

coupled with later device tree changes enables many devices on that
chip, such as MMC, I2C, etc.

This branch depends on a patch in:

git://git.linaro.org/people/mturquette/linux.git clk-for-3.10

Mike has stated that this branch is stable, and is aware of this
dependency and merge.

Mike's branch is based on v3.9-rc3, which includes a USB change which
causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
this branch pulls in v3.9-rc4 to ensure bisectability as much as
possible.

This branch is based on v3.9-rc4, followed by a merge of previous Tegra
"soc" pull request, followed by a merge of clk-for-3.10.
