arm64: dts: ti: k3-am62x-verdin: Share UART_4 MCU reservation overlay

Browse source

Verdin AM62 and AM62P both expose mcu_uart0 as Verdin UART_4, and the
reservation needed when this UART is used by the MCU firmware is
identical on both SoMs.

Rename the AM625-specific overlay added in commit ca61bcec3e ("arm64:
dts: ti: k3-am62-verdin: Reserve UART_4 for Cortex-M4F") to a common
k3-am62x-verdin overlay and use it for both AM625 and AM62P5 Verdin
combined DTBs. This avoids carrying identical SoC-specific overlays for
each remoteproc firmware/peripheral combination.
