A generic version should replace this later.

Defining iounmap() with arguments prevents it from being used as a
function pointer, causing platforms to work around this.  Instead,
define it to be a simple macro.

Do the same for __arch_io(re|un)map too.

This patch takes out IO mapping macros from mach/io.h and puts them in
mach/hardware.h avoiding need to include mach/io.h in various files such as
serial.h, vmalloc.h etc.

The main reason to avoid inclusion of mach/io.h is, when default in/out macros
are overridden by machine specific functions (e.g., in case of PCI I/O), they
result into linker error. An example snippet and error snapshot is listed below.

Following code in mach/io.h:

	#define inl(p)  my_inl()

	static inline unsigned int my_inl(unsigned int addr)
	{
		if (IS_PCI_IO(addr))
			return pci_inl ();
		else
			return le32_to_cpu(__raw_readl(__typesafe_io(addr)));
	}

leads to error:
	LD      arch/arm/boot/compressed/vmlinux
	arch/arm/boot/compressed/misc.o: In function `my_inl':
	misc.c:(.text+0x2744): undefined reference to `pci_inl'
	make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1

This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c
through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built
into compressed vmlinux.

Add arch-specific ioremap() which uses any existing static mappings in
place of doing a new mapping.  From now on, drivers should always use
ioremap() instead of IO_ADDRESS().

In addition, remove the davinci_[read|write]* macros in favor of using
ioremap.

As Al did for Versatile in 2ad4f86b,
add a typesafe __io implementation for platforms to use.  Convert
platforms to use this new simple typesafe implementation.

This just leaves include/asm-arm/plat-* to deal with.

Add base kernel support for the TI DaVinci platform.

This patch only includes interrupts, timers, CPU identification,
serial support and basic power and sleep controller init.  More
drivers to come.
