arm64: dts: ti: k3-j721e-sk: Fix pinmux for pin Y1 used by power regulator

The SoC pin Y1 is incorrectly defined in the WKUP Pinmux device-tree node
(pinctrl@4301c000) leading to the following silent failure:

    pinctrl-single 4301c000.pinctrl: mux offset out of range: 0x1dc (0x178)

According to the datasheet for the J721E SoC [0], the pin Y1 belongs to the
MAIN Pinmux device-tree node (pinctrl@11c000). This is confirmed by the
address of the pinmux register for it on page 142 of the datasheet which is
0x00011C1DC.

Hence fix it.
