Subject: [PATCH 4.19 053/321] ARM: debug-imx: only define DEBUG_IMX_UART_PORT if needed

From: Uwe Kleine-König <u.kleine-koenig@...gutronix.de>

[ Upstream commit 7c41ea57beb2aee96fa63091a457b1a2826f3c42 ]

If debugging on i.MX is enabled DEBUG_IMX_UART_PORT defines which UART
is used for the debug output. If however debugging is off don't only
hide the then unused config item but drop it completely by using a
dependency instead of a conditional prompt.

This fixes DEBUG_IMX_UART_PORT being present in the kernel config even
if DEBUG_LL is disabled.
