This fixes a build failure with CONFIG_CACHE_L2X0=n:
arch/arm/mach-imx/built-in.o: In function `imx3_init_l2x0':
imx53-dt.c:(.init.text+0x190): undefined reference to `l2x0_init'
make[2]: *** [.tmp_vmlinux1] Error 1
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2
When the l2 cache isn't enabled the quirk introduced in
9524705 (MX35: Fix bogus L2 cache settings) doesn't need to be done
either.

Pull a few more ARM platform fixes from Olof Johansson:
"Apologies for back-to-back fixes pull requests, but one of the patches
below are the kind we'll see posted over and over if we don't send it
in. I hadn't done the full sanity-check of defconfig builds by the
time I sent up the other fixes yesterday or I would have included it
then.
Two patches, one dealing with the system.h fallout, the other is a
missing linux/bug.h in a place where ARRAY_SIZE() is used."

This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.
I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

It was observed on a mx31pdk board that audio playback only worked when the bootloader was Redboot, and
did not work when U-boot was used.
Comparing the sources of these bootloaders showed that the AIPS registers were not setup in U-boot.
Instead of relying on the bootloader to setup the AIPS registers, do it in the kernel so that audio
playback can work independantly of the bootloader being used.
Copied the AIPS settings from Redboot to the kernel.

The LPM field of register CCMR is used to select the mode that the processor will run
when it goes to WFI.
When mx31 enters in WFI mode the LPM field is at its reset value of 0,
which configures the mx31 to enter in "wait mode".
On mx35, the LPM field on mx35 is also at 0 after reset, which corresponds
to "run mode" instead of "wait mode".
Instead of relying on the reset value of LPM to set the low power mode for
WFI, configure mx31 and mx35 to run in "wait mode"

The function imx3_init_l2x0() references
the function __init l2x0_init().
This is often because imx3_init_l2x0 lacks a __init
annotation or the annotation of l2x0_init is wrong.

Pull #1 ARM updates from Russell King:
"This one covers stuff which Arnd is waiting for me to push, as this is
shared between both our trees and probably other trees elsewhere.
Essentially, this contains:
- AMBA primecell device initializer updates - mostly shrinking the

reasonable.
- Getting rid of the NO_IRQ crap from AMBA primecell stuff.
- Nicolas' idle cleanups. This in combination with the restart
cleanups from the last merge window results in a great many

The mxc_init_l2x0() should really be an imx31/35 specific call.
The patch removes early_initcall from mxc_init_l2x0() and get imx31
and imx35 soc specific function calls mxc_init_l2x0(), so that it's
not necessarily to be called for all imx socs when we build single
image for multiple imx socs.
Thus the function can be renamed to imx3_init_l2x0() and put into
mm-imx3.c. It also changes the return type from integer to void.
From what I see, the integer was picked just to satisfy early_initcall
prototype.
With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code
compiles even without CONFIG_CACHE_L2X0 enabled.
