01464226ac ARM: make mach/gpio.h headers optional
Most platforms don't need mach/gpio.h and it prevents multi-platform
kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it
if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX
or have lots of implicit includes pulled in by mach/gpio.h.

at91 and omap have gpio clean-up pending and can drop
CONFIG_NEED_MACH_GPIO_H once that is in.

5df33a62c4 SPEAr: Switch to common clock framework

5019f0b134 ARM: spear: remove most mach/*.h header contents
The register and irq definitions in mach/*.h for spear3xx and
spear6xx are now mostly obsolete, after the platforms have been
converted to device tree based probing and the data is now
part of the device tree files.

The misc_regs.h contents are moved into clock.c because that is
the only user, aside from the DMA_CHN_CFG that should eventually
get handled differently. Some of the contents of mach/spear.h
still remain, because they are used to set up the static map table,
timer, uart and auxdata tables, but almost everything got removed.
We might remove everything but the map table as the DT conversion
completes, but that is not a priority. I've also made sure to
make both copies of spear.h more or less identical so we can
eventually combine them.

The spear3?0.h files were only used by the spear3?0.c files, so I
merged the contents in there and removed the bits that were unused.
This is something that should still be looked at.

c5fa4fdcdb ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture
This patch adds a generic target for SPEAr3xx machines that can be configured
via the device-tree. Currently the following devices are supported via the
devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT
- Synopsys DW I2C
- Synopsys DW ethernet
- ST FSMC-NAND
- ST SPEAR-SMI
- ST SPEAR-KEYBOARD
- ST SPEAR-RTC
- ARASAN SDHCI-SPEAR
- SPEAR-EHCI
- SPEAR-OHCI

Other peripheral devices will follow in later patches.

This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
4K for individual peripherals. This is done to have efficient TLB lookup for any
I/O windows that are located closely together. ioremap() on this range will
return this mapping only instead of creating another.

aa3831cf9d ARM: Consolidate the clkdev header files
Now most of ARM machines has the alsmot same __clk_get/put() macro

So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files

But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config

Now there are only 3 caese.

1) define the clk structure with clkdev macro => Need to move clk structure to proper header file

arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h

2) export the __clk_get/put function at clock.c

arch/arm/mach-shmobile/include/mach/clkdev.h

3) demuxing the clk source
arch/arm/mach-u300/include/mach/clkdev.h
