[PATCH v5 09/16] tests/qtest: Update tests using PL011 UART

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

We weren't enabling the PL011 TX UART before using it
on the raspi and virt machines. Update the ASM code
prefixing:

  *UART_CTRL = UART_ENABLE | TX_ENABLE;

to:

  while (true) {
      *UART_DATA = 'T';
  }
