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].
