docs(a3k): update documentation about DEBUG mode for UART
DEBUG mode can be enabled without any issue for Armada 37xx and also for
other A7K/A8K/CN913x. There is no incompatibility with Xmodem protocol
like it was written before, because Armada 37xx UART images do not print
anything on UART during image transfer and A7K/A8K/CN913x BLE image
automatically turn off debugging output when booting over UART. Looks
like this incorrect information is some relict from the past.

- DEBUG
Default is without debug information (=0). in order to enable it use ``DEBUG=1``.
- Must be disabled when building UART recovery images due to current console driver
- implementation that is not compatible with Xmodem protocol used for boot image download.
+ Can be enabled also when building UART recovery images, there is no issue with it.
+
+ Production TF-A images should be built without this debug option!
