From: Franz Schnyder <franz.schnyder at toradex.com>
On the SMARC iMX95 the WiFI UART and JTAG signals are shared. The
WIFI_UART_EN signal is used to select between these two modes.
Currently, there is no hog present in the device tree but the
configuration needs to be added, as once the device tree comes from
mainline Linux, a hog will drive WIFI_UART_EN high to select by
default the UART function during boot.
Enable CONFIG_GPIO_HOG to apply gpio-hog definitions in the device tree.
