arm64: dts: ti: k3-am62p: Add gpio-ranges for mcu_gpio0

Commit d72d73a4 ("arm64: dts: ti: k3-am62p: Add gpio-ranges
properties") introduced pinmux range definition for gpio-ranges, however
missed introducing the range description for the mcu_gpio node. As a
result, automatic mapping of GPIO to pin control for mcu gpios is
broken. Fix this by introducing the proper ranges.
