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

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:
