Find and unwrap wrapped strings in the style:

	pr_debug("clockdomain: hardware cannot set/clear wake up of "
		 "%s when %s wakes up\n", clkdm1->name, clkdm2->name);

Keeping these strings contiguous seems to be the current Linux kernel
policy.

The offending lines were found with the following command:

    pcregrep -rnM '"\s*$\s*"' arch/arm/*omap*

While here, some messages have been clarified, some pr_warning(
... calls have been converted to pr_warn( ..., and some printk(KERN_*
... have been converted to pr_*.

Some of them are pretty good catches, such as gpio.c:56 and

Thanks to Jarkko Nikula for some comments on the sscanf() warnings.
It seems that the kernel sscanf() ignores the field width anyway for the
%d format, so those changes have been dropped from this second version.

Thanks to Daniel Marjamäki <daniel.marjamaki@gmail.com> for pointing
out that a variable was unnecessarily marked static in the
board-omap3evm.c change.

gcc can apparently handle stack-allocated arrays that use a dynamic
variable as the array maximum.  Rather than using a mutable quantity,
simply use a constant maximum possible size.  To me, code clarity is
improved; and it also avoids the following sparse warnings:

arch/arm/plat-omap/dma.c:886:40: error: bad constant expression
arch/arm/plat-omap/dma.c:892:17: error: cannot size expression
arch/arm/plat-omap/dma.c:970:40: error: bad constant expression
arch/arm/plat-omap/dma.c:972:17: error: cannot size expression

Also drop some dead code from the OMAP1 LCD DMA code:

arch/arm/mach-omap1/lcd_dma.c:80:6: warning: symbol 'omap_set_lcd_dma_src_port' was not declared. Should it be static?

There's no need to have these in plat/io.h.

While at it, clean up the includes to group them
like they typically are grouped.

This patch fixes bug introduced in revision:

f8e9e984
omap1: DMA: move LCD related code from plat-omap to mach-omap1

The code introduced by this patch didn't consider any other CPUs but OMAP1510,
which rendered OMAP310 -- which has the same LCD controller -- non-working. Use
cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue.

Bug found on Palm Zire 71 hardware.

Otherwise multi-omap1 configurations will fail.

The patch corrects the issue introduced with one of my earlier patches:
	OMAP: DMA: Fix omapfb/lcdc on OMAP1510 broken when PM set[1]
as pointed out by OMAP subsystem maintainer.

Applies on top of my prevoius patch:
  OMAP: DMA: move LCD DMA related code from plat-omap to mach-omap1[2]

Tested on Amstrad Delta
Compile tested with omap_generic_2420_defconfig

All of the LCD DMA code in plat-omap/dma.c appears to be OMAP1-only (and
apparently only is available on a subset of OMAP1 chips).

Move this code to mach-omap1/lcd_dma.c.

Tested on OMAP1510 Amstrad Delta.
Compile-tested with omap_generic_2420_defconfig.
