dm: mips: Import libgcc components from Linux
Import ashldr3, ashrdi3 and lshrdi3 to squash possible libgcc fp mismatch,
resulting in the following warning:
mips-linux-gnu-ld: Warning: /usr/lib/gcc/mips-linux-gnu/4.7/libgcc.a(_lshrdi3.o) uses hard float, u-boot uses soft float
mips-linux-gnu-ld: Warning: /usr/lib/gcc/mips-linux-gnu/4.7/libgcc.a(_ashldi3.o) uses hard float, u-boot uses soft float
Imported from Linux (linux-next 20120723) as of commit:
commit 72fbfb260197a52c2bc2583f3e8f15d261d0f924

[MIPS] Fix optimization for size build.
It took a while longer than on other architectures but gcc has finally
started to strike us as well ...
This also fixes the damage by 6edfba1b33c701108717f4e036320fc39abe1912.
