MIPS: Cleanup and Fixup of compressed kernel support
o Remove the .initrd section. The initrd section was already handled
when vmlinux was linked.
o Discard .MIPS.options, .options, .pdr, .reginfo, .comment and .note
sections. If .MIPS.options is not removed, kernels compiled with gcc
3.4.6 will not boot.
o Clean up the file format.
o Remove several other unneeded sections.
Tested with GCC 3.4.6 and 4.4.1 with and without initrd.
