[SRU][N:raspi][PATCH 6/7] dts: bcm2712: cm5: Force the ANT pins to GPIOs

[Juerg Haefliger]

From: Phil Elwell <phil at raspberrypi.com>

BugLink: https://bugs.launchpad.net/bugs/2089555

The magic required to make requesting a GPIO automatically change the
pinmux settings is currently absent. Work around that by explicitly
requesting that the ANT pins be in GPIO mode.
