Vadim Bendebury e63990ef34 libpayload: provide basic 64bit division implementation
These functions are usually provided by gcc lib, which is not supposed
to be included on embedded platforms. This patch adds a no thrills C
implementation.

Other than MIPS platforms are happy using the gcc library provided
implementation, but in case of Chrome OS MIPS toolchain the libraries
are compiled with the small GOT, such that the entire data segment
does not fit.

With this implementation mips, arm and x86 targets build fine.

BRANCH=none
BUG=chrome-os-partner:31438

TEST=checked the logic by incorporating this code into a C file and
     running a loop continuously comparing random inputs' division and
     left and right shift results.

     The test ran for extended periods of time without failure.
