soc/skl/vr_config: set Iccmax_gt depends on CPU/GT
According to the DC Current Specifications [1], the current limit for
the graphical VR domain (Iccmax_gt) isn't same for different Kaby Lake S
CPUs. This value should depend on the iGPU model and processor TDP:
+---------------------+-----+------------+
| Segment | TDP | Icc_max GT |
+---------------------+-----+------------+
| Dual Core GT2/GT1 | 35W | |
| Dual Core GT2 | 51W | 48 A |
| Dual Core GT1 | 54W | |
+---------------------+-----+------------+
| Quad Core GT2 | 35W | 35 A |
+---------------------+-----+------------+
| Quad Core GT2 | 65W | 45 A |
| Quad Core GT2 K-SKU | 91W | |
+---------------------+-----+------------+
This patch adds the remaining Iccmax_gt current limit values from the
documentation [1].
