pm: cpupower: Add header changes for cpufreq.h to SWIG bindings

"cpupower: Add support for showing energy performance preference" added
two new functions to cpufreq.h. This patch adds them to the bindings.

Link: https://lore.kernel.org/linux-pm/[email protected]/T/#t

Tested by compiling both libcpupower and the headers; running the test
script that does not use the functions as a basic sanity test.
