[PATCH] intel_idle: Add Jasper Lake and Elkhart Lake support

[Kai-Heng Feng]

Without proper C-state support, the CPU can take long time to exit to C0
to handle IRQ and perform DMA.

The data collect via wult shows the latency is similar to Broxton, so
use the existing table to support C-state on JSL and EHL.
