arm64: dts: ti: k3-j742s2-mcu-wakeup: Override firmware-name for MCU R5F cores

The J742S2 SoC reuses the common k3-j784s4-j742s2-mcu-wakeup-common.dtsi
for its MCU domain, but it does not override the firmware-name property
for its R5F cores. This causes the wrong firmware binaries to be
referenced.

Introduce a new k3-j742s2-mcu-wakeup.dtsi file to override the
firmware-name property with correct names for J742s2.
