plat: imx: imx8qm: apply clk/pinmux configuration for DEBUG_CONSOLE

Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A53
doesn't make sense (since UART pinmux/clock configuration is applied
for UART only when DEBUG_CONSOLE_A53 is enabled).

Enable DEBUG_CONSOLE_A53 if DEBUG_CONSOLE is enabled.
