endian: Always evaluate arguments ...

This patch is based on

    commit 3d6f4a2

        endian: Always evaluate arguments.

In barebox.git/drivers/usb/core/usb.c,
function usb_parse_config() we have had

    le16_to_cpus(&(dev->config.wTotalLength));

which evaluates to "do { } while (0)" on little endian,
so struct usb_configuration field misuse will never
be discovered on little endian.

Therefore, always evaluate the arguments to nop endian
transformation operations.

include: Add foreign endianess adding functions from kernel ...

Change byte order detection mechanism to kernel style ...

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.
