plat: imx: imx8qx: provide debug uart num as build param
1. This removes hardcoded iomux/clk/addr configuration for debug uart,
provides possibility (as a workaround, till that information isn't
provided via DT) to set this configuration during compile time via
IMX_DEBUG_UART build flag.
Also for Colibri i.MX8QXP different pinmux configuration is applied
for UART3, FLEXCAN2_RX/TX pads are muxed to ADMA_UART3_RX/TX.
2. Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A35
doesn't make sense (since UART pinmux/clock configuration is applied
for UART only when DEBUG_CONSOLE_A35 is enabled. Check similar commit
for i.MX8QM 98a69dfd4a("plat: imx: imx8qm: apply clk/pinmux
configuration for DEBUG_CONSOLE")).
Usage:
$ make PLAT=imx8qx IMX_DEBUG_UART=3 DEBUG_CONSOLE=1 bl31
