From: Zhang Rui <rui.zhang@xxxxxxxxx> [ Upstream commit 3fb0eea8a1c4be5884e0731ea76cbd3ce126e1f3 ] Similar to the MSR RAPL interface, MMIO RAPL supports PL4 too, so add MMIO RAPL PL4d support to the processor_thermal driver. As a result, the powercap sysfs for MMIO RAPL will show a new "peak power" constraint.
