Subject: [PATCH] defconfig: Enable the HX711 load-cell ADC driver

Enable CONFIG_HX711=m in the Raspberry Pi configurations so kernel
packages include the existing IIO driver for HX711 load-cell ADCs.
This avoids requiring applications to build and maintain a separate
copy of the driver across kernel updates.

GPIO assignments still require a device-tree description.
