i915drmkms0: notice: Resetting chip for stopped heartbeat on rcs0

[Paul Ripke <stix%stix.id.au@localhost>]

Just another data point in the i915drmkms0 sagas. I had X freeze today, unable
to restart X, with the kernel reporting the below every second or 4. Reboot
required.

netbsd-10, amd64, ~2wk old kernel, Intel Sandybridge

cpu0: Intel Xeon E3-12xx, 2nd gen i7, i5, i3 2xxx (686-class), 3392.30 MHz
cpu0: family 0x6 model 0x2a stepping 0x7 (id 0x206a7)
