These patches for building 32-bit RISC-V kernel.
 - Fix the compile errors and warnings on RV32I.
 - Fix some incompatible problem on RV32I.
 - Add format.h for compatible of print format.

The fixed width integer types format for Elf_Addr will move to
generic header by another patch. For now, there are some warning
about unexpected argument of type on RV32I.

Change in v1:
 - Fix some error in v1
 - Remove implementation of fixed width integer types format for Elf_Addr.
