imx8mq allocation issue

[Heiko Thiery]

HI,

I think on the imx8mq platform we have a problem with the introduction
of the clock driver. I tried to debug the problem that the pitx-imx8m
board was not able to start for some time. I was wondering why the
pitx-im8m doesn't work anymore although the imx8mq_evk is running.

So I switched to the imx8mq_evk for counter testing. As I already
figured out in [1] also the imx8mq_evk is not able to start properly.

On the EVK I enabled the DEBUG_UART and see the outputs below. I
suspect all imx8mq boards have this problem.

CONFIG_DEBUG_UART_BASE=0x30860000      # for uart1
CONFIG_DEBUG_UART_CLOCK=24000000

Could the maintainers of the other imx8mq boards please check if they
can confirm this?
