This patch was previously included in the below SA8775P DDR & L3 scaling
series:

https://lore.kernel.org/all/20241112-sa8775p-cpufreq-l3-ddr-scaling-v2-0-53d256b3f2a7@quicinc.com/

Based on Bjorn's review comments on the above series, included DDR & L3
scaling patch in it's dependent interconnect series and posting the LMH
interrupts patch separately here.
