Move power control related definitions to power_control.h
Now that we have separate header/code files for the power control, let's move the related definitions there. This change makes the code consistent with osmo-bts, where it's already done this way. Change-Id: I1cb3f6bfba0306e8f371dcd5162d1813beb3a088
