Subject: [PATCH] arm64: dts: qcom: hamoa: fastrpc: set ADSP on secure domain

On Hamoa platforms, ADSP FastRPC should be instantiated as a secure
domain. The presence of `qcom,non-secure-domain` under the ADSP fastrpc
node causes the kernel to expose a non-secure device node, which is not
desired for Hamoa.
