commonlib/bsd/lz4_wrapper.c: Fix misaligned access
Currently the HiFive Unleashed produces the following exception: [DEBUG] Exception: Load address misaligned [DEBUG] Hart ID: 0 [DEBUG] Previous mode: machine [DEBUG] Bad instruction pc: 0x080010d0 [DEBUG] Bad address: 0x08026ab3 [DEBUG] Stored ra: 0x080010c8 [DEBUG] Stored sp: 0x08010cc8 The coreboot LZ4 decompression code does some misaligned access during decompression which the FU540 apparently does not support in SRAM. Make the compiler generate code that adheres to natural alignment by fixing the LZ4_readLE16() function and creating LZ4_readLE32().
