There are no generic native ordered io accessors. This sometimes
leads to
v = in_be32(a);
v = readl(a);
in generic drivers. Instead, use io accessors which are explicitely
native ordered.

This provides some generic io accessors for architectures which
do not need special handling.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

This patch adds the m25p80 driver. It has been ported from
Linux. MTD code has been removed. It has been tested with
a m25p40 chip and the Altera SPI master driver.

In barebox we used 1MiB sections to map our SDRAM cachable. This
has the drawback that we have to map our sdram twice: cached for
normal sdram and uncached for DMA operations. As address space gets
sparse on newer systems we are sometines unable to find a suitably
big enough area for the dma coherent space.
This patch changes the MMU code to use second level page tables.
With it we can implement dma_alloc_coherent as normal malloc, we
just have to remap the allocated area uncached afterwards and map
it cached again after free().
This makes arm_create_section(), setup_dma_coherent() and mmu_enable()
noops.

The first resource may not be a IORESOURCE_MEM at all.

During the creation of a new spi device, we need to
have the possiblility to give the bits_per_word value
to master->setup.
As a matter of fact, spi master could check the spi
device bits_per_word and compare this value against its
capabilities.

The current version of struct stat has been taken from an
ancient Linux Kernel. It looks different on different architectures
to support different userspace formats of struct stat. As we do
not have a userspace on barebox there is no need to keep different
versions.
Also, this unification make MIPS arch possible.

While getting rid of all the format(barebox_printf) warnings was nice,
it caused the printf calls in arch/sandbox/os/common.c to get directed
to the barebox versions rather than the libc ones causing a crash:
E.G. before this revert:
nm -a barebox|grep -w printf
0000000000404fa3 T print
And after:
nm -a barebox|grep -w printf
U printf@@GLIBC_2.2.5
