stm32h7: enable the fast PLL on-demand
Add a new module ID 'MODULE_FAST_CPU'.
When it is enabled with clock_enable_module(MODULE_FAST_CPU, 1), switch
the system clocking to the fast 400-Mhz PLL.
For now, I consider that a single task/user is calling
clock_enable_module(MODULE_FAST_CPU, x), so we don't need to count users
(in a complicated atomic fashion). It's good enough for the current
use-case and we can add the complexity later if we have a real need.
BRANCH=none
BUG=b:67081508
TEST=on ZerbleBarn, with follow-up CL setting
clock_enable_module(MODULE_FAST_CPU,x) around the computation block,
see that computations are fast and the clock goes back to HSI after.
