Subject: [PATCH resend] arm64: dts: mediatek: mt8192: Mark scp_adsp clock as broken

The scp_adsp clock controller is under the SCP_ADSP power domain. This
power domain is currently not supported nor defined.

Mark the clock controller as broken for now, to avoid the system from
trying to access it, and causing the CPU or bus to stall.
