3c1722e705 stm32: Fix extraction of hse/hsi/pllm values from preprocessed source. 
The expressions for the `micropy_hw_hse_value` etc variables may contain
parenthesis, eg `micropy_hw_hse_value = ((25) * 1000000)`.  To handle such
a case, simplify the regex and always use `eval(found)` to evaluate the
expression.

58112fc49a stm32/machine_i2s: Improve accuracy of SCK frequency. 
Configures the I2S PLL to produce a frequency that the I2S clock generator
can use to create an optimal SCK frequency.  The I2S PLL configuration
table is automatically generated at build time.

Fixes issue #10280.
