m32r: Move defconfig files to arch/m32r/configs/

Change defconfig file's location from arch/m32r/{platform}/defconfig*
to arch/m32r/configs/{platform}_defconfig.

Applying this patch, we can use defconfig file for each m32r platform
easily, like other architectures.

  ex. Setup defconfig for cross-building
    $ make ARCH=m32r CROSS_COMPILE=m32r-linux-gnu- {platform}_defconfig.
