dts: bcm2712: cm5: Force the ANT pins to GPIOs

pelwell · pelwell · commit 0c341f47adc3 · 2024-04-19T09:55:36.000+01:00
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.
