Subject: [PATCH RFT] arm64: dts: qcom: sc7280: Add missing LMH interrupts

Hook up the interrupts that signal the Limits Management Hardware has
started some sort of throttling action.

Fixes: 7dbd121a2c58 ("arm64: dts: qcom: sc7280: Add cpufreq hw node")
Signed-off-by: Konrad Dybcio <[email protected]>

test case:

- hammer the CPUs (like compile the Linux kernel)
- watch -n1 "cat /proc/interrupts | grep dcvsh"
- the numbers go up up up up -> good
