lspci -nnk and dmesg output

After updating from kernel 4.9 series to 4.10 series I have identified a
regression when using the discrete GPU on my laptop (Lenovo Thinkpad E560).

When running any demanding application with DRI_PRIME=3D1 the card will han=
g, one
example would be running 'DRI_PRIME=3D1 glmark2 -b texture'.

I have noticed that the content of /sys/kernel/debug/dri/1/radeon_pm_info h=
as
changed between kernel 4.9 and 4.10 when running glmark2.

With 4.9:
power level 4    sclk: 75000 mclk: 80000 vddc: 1050 vddci: 0 pcie gen: 2

With 4.10:
power level 4    sclk: 87500 mclk: 90000 vddc: 1050 vddci: 0 pcie gen: 2

This led me to revert commit 3a69adfe5617ceba04ad3cff0f9ccad470503fb2 which
prevents the card from hanging.

You can find the output of lspci and dmesg in the attachment for the case w=

commit 3a69adfe5617ceba04ad3cff0f9ccad470503fb2 reverted.
