Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available. But this doesn't always work.
We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources. And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.
With this change, each $(CPU)/ directory can have its own timer code.

Au1x00 is a SoC and its specific code should reside in an own
SoC subdirectory. Also add -mtune=4kc flag for CPU optimization.

All current CPUs and SoCs are based on MIPS32 arch. The complete
code resides in the global arch/mips/cpu directory. This is not
suitable if other MIPS architectures like MIPS64 or Octeon should
be supported in the future.
To achieve this the current CPU code is moved to its own mips32
subdirectory. All MIPS32 boards have to use mips32 as config switch
in board.cfg.
