Subject: [PATCH 0/2] Fix a __clk_core_init parental issue

Mark and Alexander, please test to see if these patches resolve the
issues on your boards.

I expect the first patch to completely fix the problem on the Avenger96
(STM32MP1) board.

I'm less sure about the i.MX8MP board. I believe the second patch is
needed there, but I don't know for certain, as I don't have the hardware
to test.
