Julien Panis 169582025a arm64: mach-k3: am625_init: Probe ESM nodes
On AM62x devices, main ESM error event outputs can be routed to
MCU ESM as inputs. So, two ESM device nodes are expected in the
device tree : one for main ESM and another one for MCU ESM.
MCU ESM error output can trigger the reset logic to reset
the device when CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is
set to '0'.
