There are no conflicting files between the three mach-spear* directories
and plat-spear any more, so we can now move all file to a common
mach-spear directory.

As an intermediate step towards unification of the three spear
platforms, this gets rid of the mach/* header files that are
obviously not platform specific.

This patch adds basic header files for SPEAr13xx Machines.

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.

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.

This patch makes inclusion of hardware.h and spear.h consistent over all spear
variants. Now we will include hardware.h, wherever we need to use hardware
macros. spear.h will be automatically included by hardware.h

Add IOMEM(x) definition, and use it with MISC_BASE for SPEAr platform.
With this there is no need to typecast misc macros to (unsigned int *).
