soc/amd/picasso: Drop _INI and OSFL methods 

This change drops _INI and OSFL methods under \_SB since they are not doing
anything useful. _INI only calls OSFL and OSFL initializes OSVR if not
already initialized and returns OSVR value. However, OSVR is not used
anywhere and hence both these functions can be dropped.
