updated {amd_pm_funcs}->get_power_limit() signature
rewrote pp_get_power_limit to use new enums
pp_get_power_limit now returns -EOPNOTSUPP for unknown power limit
update calls to {amd_pm_funcs}->get_power_limit()
* Test Notes
* testing hardware was NAVI10 (tests SMU path)
** needs testing on VANGOGH
** needs testing on SMU < 11
** ie, one of
TOPAZ, FIJI, TONGA, POLARIS10, POLARIS11, POLARIS12, VEGAM, CARRIZO,
STONEY, VEGA10, VEGA12,VEGA20, RAVEN, BONAIRE, HAWAII
* Test
