ARM64: dts: radxa0_4g: Use safe value for usable memory end region

Although the previous value (the maximum within the 32-bit range)
booted fine when dtb.img was normally flashed in bootloader mode,
it proved to cause issues when fully packed image was flashed
via AML flash tool.

This value has been taken from S922X datasheet. Stick to it as
the user facing total memory is 4.0 GB, as desired.
