Subject: [PATCH] arm64: dts: ti: k3-j722s-evm: Fix USB gpio-hog level for Type-C

According to the "GPIO Expander Map / Table" section of the J722S EVM
Schematic within the Evaluation Module Design Files package [0], the
GPIO Pin P05 located on the GPIO Expander 1 (I2C0/0x23) has to be pulled
down to select the Type-C interface. Since commit under Fixes claims to
enable the Type-C interface, update the property within "p05-hog" from
"output-high" to "output-low", thereby switching from the Type-A
interface to the Type-C interface.
