What configuration exact?
How is it broken?
What are the messages when printed compiling stm32_clk when "CLOCK_DEBUG" is
defined in stm32_clk.

Clock setup was largely rewritten to work without the need to set
SYSCLK_FREQ when using a standard frequency as input. Compiling the uspsf107
configuration with CLOCK_DEBUG at least prints out the expected messages.
