arm64: dts: ti: k3-am68-sk-base-board: Update IO EXP GPIO lines for Rev E2

Rev E2 of the AM68 SK baseboard has updated the GPIO IO expander pins
functionality. To match the Rev E2 schematics, update existing IO expander
GPIO line names and the corresponding node which uses the expansion(exp1)
node.
