Remove unnecessary **kwargs from spa_python and get_total_irradiance (#1437)

* Update Solarposition.py

Removed **kwargs from pvlib.solarposition.spa_python

* Added v0.9.2.rst, changes in pvlib/irradiance.py and pvlib/location.py

Made new v0.9.2.rst and removed **kwargs from pvlib/irradiance.py (Line 309) and pvlib/location.py (Line 234-235)

* Update docs/sphinx/source/whatsnew/v0.9.2.rst

* Update docs/sphinx/source/whatsnew/v0.9.2.rst
