arm64: dts: ti: k3-j721e-common-proc-board: Disable unused gpio modules

Browse Source 
There are 10 gpio instances inside SoC with 3 groups as below:
- Group1: main_gpio0, main_gpio2, main_gpio4, main_gpio6
- Group2: main_gpio1, main_gpio3, main_gpio5, main_gpio7
- Group3: wkup_gpio0, wkup_gpio1

Only one instance can be used in each group at a time. So use main_gpio0,
main_gpio1 and wkup_gpio0 for the current linux context and mark other
gpio nodes as disabled.
