[Intel-gfx] [PATCH V4 1/6] drm/i915: Split the BDW device definition to prepare for dual BSD rings on BDW GT3

[Zhao Yakui]

Based on the hardware spec, the BDW GT3 has the different configuration
with the BDW GT1/GT2. So split the BDW device info definition.
This is to do the preparation for adding the Dual BSD rings on BDW GT3 machine.

V1->V2: Follow Daniel's comment to pay attention to the stolen check for BDW
in kernel/early-quirks.c
