drm/radeon: reduce sparse false positive warnings include radeon_asic.h header file in the various xxx_dpm.c files to reduce sparse false positive warnings. Not so great patch in itself, but reducing warning count from 391 to 258 may help to see real problems..

drm/radeon/pm: move pm handling into the asic specific code We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
