arm64: dts: qcom: ipq8074: move ARMv8 timer out of SoC node

The ARM timer is usually considered not part of SoC node, just like
other ARM designed blocks (PMU, PSCI).  This fixes dtbs_check warning:

arch/arm64/boot/dts/qcom/ipq8072-ax9000.dtb: soc: timer: {'compatible': ['arm,armv8-timer'], 'interrupts': [[1, 2, 3848], [1, 3, 3848], [1, 4, 3848], [1, 1, 3848]]} should not be valid under {'type': 'object'}
