include: asm-generic: don't do 64-bit soft division on 64-bit platforms
barebox implements do_div() as soft division unconditionally, even on
64-bit platforms that could use hardware 64-bit division directly.
Import the whole Linux asm-generic/div64.h header to avoid this.
This also has potential positive effect on 32-bit platforms:
64-bit division with constant divisors can now be optimized into
multiplications and shifts at compile time.
