Subject: [PATCH] arm64: dts: qcom: ipq5424: correct the TF-A reserved
 memory to 512K

Correct the reserved memory size for TF-A to 512K, as it was mistakenly
marked as 500K. Update the reserved memory node accordingly.

Fixes: 8517204c982b ("arm64: dts: qcom: ipq5424: Add reserved memory for TF-A")
