This patch adds the clock driver of exynos5420. This driver is almost
same with the one in mainline linux kernel. There are too many commits
to this driver and the gap between exynos clock framework in Tizen 3.10
and Linux mainline 3.18 makes it hard and meaningless(in my opinion) to
get the original patches. So I modified only the interface between this
and the core of exynos clock framework to make it adoptable in Tizen
kernel 3.10.

PLL35xx and PLL2550 are very similar, and so they share the code for
their control. PLL2550 in Exynos5422 have different offsets to control
register from the base of them. mainline linux have the variable for it.
But because of too much difference between the mainline linux and
Tizen 3.10. It cannot be adopted with few commits. So I made this patch
to accomplish this purpose with small changes.

The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.
The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.
Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

This patch does the following in exynos5_i2c_message_start() function
1. Fixes an assignment
As, "i2c_auto_conf" is initialized to '0' at the beginning of the
function and HSI2C_READ_WRITE is defined as (1u << 16)
Using "|=" for the first assignment is more readable.

The original code for the exynos i2c controller registered for the
"noirq" variants. However during review feedback it was moved to
SIMPLE_DEV_PM_OPS without anyone noticing that it meant we were no
longer actually "noirq" (despite functions named
exynos5_i2c_suspend_noirq and exynos5_i2c_resume_noirq).
i2c controllers that might have wakeup sources on them seem to need to
resume at noirq time so that the individual drivers can actually read
the i2c bus to handle their wakeup.
NOTE: I took the original review feedback from Wolfram and added
poweroff, thaw, freeze, restore.
This patch has only been compile-tested since I don't have all the
patches needed to make my machine using this i2c driver actually
suspend/resume.

HSI2C module on Exynos5260 differs from current modules in
following ways:
1. HSI2C on Exynos5260 has fifo_depth of 16bytes
2. Module needs to be reset as a part of init sequence.
Hence, Following changes are involved.
1. Add a new compatible string and Updates the Documentation dt bindings.
2. Introduce a variant struct to support the changes in H/W
3. Reset the module during init. Thus, bringing the module back
to default state irrespective of what firmware did with it.

The changes introduced provide support for FIMC-IS
subsystem avalilable on Exynos3250.
They cover the differences in both: the hardware itself
as well as the subtle discrepancies between the firmwares
controlling the FIMC IS on both SoCs.
Regarding the above mentioned firmware variations:
the initial driver has been extended with a simplified
interface handling those variations thus living the core
driver independent of the actual firmware version.
Missing code paths have been added to cover handling some of
the most probable failures/errors.
