mips: Add mips/ashldi3.c from Linux

As MIPS toolchain does not provide adequate support for 64 bit
division and shift operations, the missing functions are required to
be provided by the user.

This patch brings in the Linux implementation of the 64 bit arithmetic
shift borrowed from arch/mips/lib/ashldi3.c (eg. Linux v3.14).

BUG=chromium:406038
TEST=With the upcoming patches coreboot successfully builds for MIPS
     targets in chroot (coming later).
