Subject: [PATCH 1337/2940] drm/amd/powerplay: add interface to init power (v2)
This patch adds interface to init power function for smu.
It's to create smu_power_context structure, and allocate smu_dpm_context and
context size to fill the smu_power_context data.
v2: add detailed info to describe this function
