arm64: dts: k3-am623-pfc-750-84xx-baseboard: move KSZ9477 reset pin to MCU GPIO

Browse Source 
Move the reset GPIO pin for the KSZ9477 Ethernet switch from main_gpio1
pin 10 to mcu_gpio0 pin 11 to match the actual hardware configuration.

This change:
- Removes the reset pin definition from main_pmx0 pinctrl group
- Adds a new mcu_pmx0 pinctrl group for the MCU GPIO configuration
- Updates the ksz9477 device node to reference both pinctrl groups
- Changes reset-gpios from main_gpio1 10 to mcu_gpio0 11
