powerpc/ppc32: static ftrace fixes for PPC32

Impact: fix for PowerPC 32 code

There were some early init code that was not safe for static
ftrace to boot on my PowerBook. This code must only use relative
addressing, and static mcount performs a compare of the
ftrace_trace_function pointer, and gets that with an absolute address.
In the early init boot up code, this will cause a fault.

This patch removes tracing from the files containing the offending
functions.
