drm/amd/pm/powerplay/smumgr: Fix PCIeBootLinkLevel value on Iceland
[ Upstream commit 501672e3c1576aa9a8364144213c77b98a31a42c ]
Previously this was initialized with zero which represented PCIe Gen
1.0 instead of using the
maximum value from the speed table which is the behaviour of all other
smumgr implementations.
Fixes: 18aafc59b106 ("drm/amd/powerplay: implement fw related smu interface for iceland.")
