Move more RF path stuff (initialization and MAX5864 state management) into rf_path.c.

Browse Source 
Changed initial RF path mode to lowest power (OFF).
Remove initial MAX2837 IF setting -- it's a waste of effort when the first (and necessary) tuning operation will reset it anyway (perhaps to a different value).
