[RFC PATCH v2 08/33] power: rename variable to eliminate shadowing

[Bruce Richardson <bruce.richardson@intel.com>]

The "pause_duration" variable is a global and then shadowed as a local
var in clb_pause. Rename the local variable to allow building with
"-Wshadow".

Fixes: 4a8fbc28e431 ("power: add get/set pause duration API")
