ARM: SAMSUNG: Fix null pointer dereference in ADC driver

NULL) when checking for SoC type.

4f2b617aff ARM: SAMSUNG: Move gpiolib support in gpio.c to plat-samsung
Move the gpio.c code containing the core gpiolib and GPIO support to
plat-samsung from plat-s3c as it is used by all current Samsung SoCs.

Note, we didn't move this to gpiolib.c as it contains code that is not
strictly for gpiolib support and the 4bit code is already called gpiolib.c
so make the change easier by not renaming both files in one go.

398ccccb77 ARM: S3C64XX: SPI: Header for passing platform data
We need a way to pass controller specific information to the SPI driver.
For that purpose new headers are made.

SPI Controller is assumed 'type-s3c64xx' and can be defined for newer SoCs.
 Hence, that part is placed under plat-samsung to be shared across newer SoCs.

SoC specific part - spi source clocks, will be placed
under plat-<soc>/include/plat/

f3b464cca9 ARM: SAMSUNG: Fix clksrc-clk's checks for bad register settings
The WARN_ON() was only checking the first clock in the array, instead of
being executed for each clksrc clock being registered.

Since this is an array of clocks, WARN_ON() does not provide a lot of
useful information about the problem, so change to using printk(KERN_ERR)
to report the problem to the console.

As a note, we still try and register the clock even if these problems are
present just in case and to avoid changing the behaviour of the registration
process.

The new code calls the clock setup code on registration which
can be before the clock system has been fully initialised. The
following code re-does this setup at the end of the clock
registration and thus we get two printings.

b3bf41be06 ARM: SAMSUNG: Reduce size of struct clk.
Reduce the size of struct clk by 12 bytes and make defining clocks with
common implementation functions easier by moving the set_rate, get_rate,
round_rate and set_parent calls into a new structure called 'struct clk_ops'
and using that instead.

This change does make a few clocks larger as they need their own clk_ops,
but this is outweighed by the number of clocks with either no ops or having
a common set of ops.

Update all the users of this.
