[PATCH] sched/doc: supplement CPU capacity with RISC-V

From: Song Shuai
Date: Mon Feb 27 2023 - 06:01:30 EST


This commit 7d2078310cbf ("dt-bindings: arm: move cpu-capacity to a
shared loation") updates some references about capacity-dmips-mhz
property in this document.

The list of architectures using capacity-dmips-mhz omits RISC-V, so
supplements it here.
