To keep panic_timeout accuracy when running under a hypervisor, the
current implementation only spins on long time (1 second) calls to mdelay.
That brings a good effect, but the problem is the keyboard LEDs don't
blink at all on that situation.
This patch changes to call to panic_blink_enter() between every mdelay and
keeps blinking in spite of long spin timer mode.
The time to call to mdelay is now 100ms. Even this change will keep
panic_timeout accuracy enough when running under a hypervisor.

dma-plat.h is the last file left in plat-s3c64xx, but to remove it we
must also change the use of dma-plat.h by the core code and the s3c24xx

may be used for other ports. Move the specific dma bits into the

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.

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.
