[PATCHv3 19/26] arm: mach-k3: do board config for PM and RM only if supported

From: Tero Kristo <t-kristo at ti.com>

If the raw PM support is built in, we are operating in the split
firmware approach mode where RM and PM support is not available. In this
case, skip the board config for these two.
