Subject: drm/amd/swSMU: add callback to set AC/DC power source (v2)
Git-commit: 2c02b38a10fc0717fadd94aab2b7eee656a3c44a
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
This is needed to tell the SMU firmware what state is in
in certain cases. DC mode does not allow overclocking
for example.
v2: split Evan's original patch (Alex)
