Navassa ADRV9001 driver missing ability to set GPIO as "TX DCLK OUT"

[esromneb]

The user's guide (https://www.analog.com/media/en/technical-documentation/user-guides/adrv9001-ug1828.pdf) states on page 260-261 that DPGIO_12 - DGPIO_15 can be configured in "TX DCLK OUT" mode / feature. When looking at the driver code, these enums are missing from typedef enum adi_adrv9001_GpioSignal

https://github.com/analogdevicesinc/linux/blob/adi-6.1.0/drivers/iio/adc/navassa/devices/adrv9001/public/include/adi_adrv9001_gpio_types.h#L150

Is there a different way to configure "TX DCLK OUT" that I'm missing? (I'm on the adi-6.1.0 branch)
