v2: add comment to highlight assignment that changes uint32_t value to int
fix errors flagged by checkpatch.pl
New Functions
smu_get_baco_capability() - Implement Powerplay API get_asic_baco_capability
smu_baco_set_state() - Implement Powerplay API set_asic_baco_state
Modified Functions
smu_read_sensor() - modifed signature to match Powerplay API read_sensor
Other Changes
added 3 above smu Powerplay functions to swsmu_dpm_funcs
removed special smu handling in 5 dpm functions and called through Powerplay
API
