[PATCH 1/2] powerpc/machdep: Drop include of seq_file.h

[Michael Ellerman]

Drop the include of seq_file.h in machdep.h, replace it with a forward
declaration of struct seq_file, which is all that's required.

Add direct includes of seq_file.h to some files that were getting
seq_file.h via machdep.h.
