Try the following steps and let me know if you are able to select and configure
the dependencies and the driver you wish to build:

   cd /path/to/linux/source/
   cp .config .config_x86_64
   cp arch/arm64/configs/defconfig .config
   make ARCH=arm64 CROSS_COMPILE=<<arm64 gcc compiler binary path>> menuconfig

Note: you first need to resolve the dependencies and then you will be presented
the selection option for your driver.

Once you configure the driver, run following to build the Kernel image and
should include your driver as well:
   make ARCH=arm64 CROSS_COMPILE=<<arm64 gcc compiler binary path>>
