For tps6594, ESM_MCU interrupts were supposed to be cleared by the MCU FW. That's why we only had to
deal with ESM_SOC interrupts in linux. For tps65224, I would recommend double-checking with TI where
ESM_MCU interrupts should be handled (either in MCU FW or in the linux driver). For some reason this
might be different than tps6594's case, but it does not look very consistent to me at first sight.
