[U-Boot] [PATCH] mmc: Use lldiv() for 64-bit division in write_raw_image()

[Siarhei Siamashka]

This fixes compilation problems when using a hardfloat toolchain on
ARM, which manifest themselves as "libgcc.a(_udivmoddi4.o) uses
VFP register arguments, u-boot does not".

These problems have been reported in the U-Boot mailing list:

I have only tested that the compilation problem disappears for
me. It would be best if somebody could confirm whether the fix
is correct.
