ARM: imx6q: let users input debug uart port number
imx6q gets 5 uart ports in total. Different board design may choose different port as debug uart. For example, imx6q-sabresd uses UART1, imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than bloating DEBUG_LL choice list with all these uart ports, the patch introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.
