Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

include/linux/time.h contains several unused functions derived from U-Boot
code. Since this is a file under include/linux/ it should contain only code
from the kernel, so remove all this.

The Linux Kernel defines only one of __LITTLE_ENDIAN and
__BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace
always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then
be tested with #if __BYTE_ORDER == __xx_ENDIAN.
As we tend to use a lot of Kernel code in barebox we switch to use the kernel
way of determing the byte order.
As this always causes a lot of confusion add a check to include/common.h to
make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined.

Change NAND_WRITE into MTD_WRITE.
Change "page_shift" references in the core, which are purely
NAND, into mtd->writesize which is MTD generic.
Rename all "info" (struct mtd_info) into "mtd".
Also provide a parameter to add_mtd_device() so that legacy
nand devices still appear as nand<N>.

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.
