MIPS: Make the debugging of compressed kernel configurable
This patch adds a new DEBUG_ZBOOT option to allow the users to enable it to debug the compressed kernel support for a new board and this optoin should be disabled to reduce the kernel image size and speed up the kernel booting procedure when the compressed kernel support is stable.
