From: Emanuele Ghidoli emanuele.ghidoli@toradex.com

MCU_CLKOUT0 output can be driven by two different clock inputs: one at 25 MHz and another at 50 MHz. Currently, the 25 MHz input clock is not selectable due to a duplication of the 50 MHz clock input in the mux configuration. This commit corrects the parent clock mux configuration, making the 25 MHz input clock selectable.
