libpayload: arch/mips: Add basic MIPS architecture support

Browse Source 
Add the basic build infrastructure and architectural support
required to build for targets using the MIPS architecture.
This will require the addition of cache maintenance.

BUG=chrome-os-partner:31438
TEST=tested on Pistachio FPGA with Depthcharge as payload;
     successfully executed payload.
BRANCH=none
