[PATCH v2] cpufreq: ia64: Remove unused header files

[Yangtao Li <tiny.windzz@gmail.com>]

seq_file.h does not need to be included, so remove it. Moreover deleted
a line of meaningless return and some useless blank lines. In a function
whose return type is void, returning on the last line is not required.
