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.

The AT2440EVB should not be changing the s3c_device_sdi.name as this is

and actually present in arch/arm/plat-s3c24xx/s3c24xx.c.

Add a driver to provide DVS for the Simtec Osiris module to reduce
the power consumption whilst idling.
The DVS driver alters the voltage supplied to the ARM core depending
on the frequency it is running at. The driver itself does not do any
of the frequency alteration, which is left up to the cpufreq driver.

Move all the gpio functions out of <mach/hardware.h> as
this file is for defining the generic IO base addresses
for the kernel IO calls.
Make a new header <mach/gpio-fns.h> to take this and
include it via the chain from <linux/gpio.h> which is
what most of these files should be using (and will be
changed as soon as possible).
Note, this does make minor changes to some drivers but
should not mess up any pending merges.

The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.
The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.
Do the following replacements:
S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT
S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT
to remove any usages of these and prepare the header for
the removal of these.
The following command was used to acheive this:
find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g'

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.
