arm64: dts: ti: k3-j721e-mcu-wakeup: Add MCU domain ESM instance

Browse source

Currently J721E defines only the main_esm in DTS. Add node for mcu_esm
as well.

According to J721E TRM (12.11.2.2 ESM Environment) [1], we see that the
interrupt line from ESMi (main_esm) is routed to MCU_ESM (mcu_esm). This
is MCU_ESM0_LVL_IN_95 with interrupt ID 95. Configure mcu_esm
accordingly so that errors from main_esm are routed to mcu_esm and
handled.
