esp32/machine_i2c: Use IDF function for calculating main timeout.

The esp32 I2C driver sets a global timeout during init.  The functionality
for this is currently only correct for original esp32 and esp32-s2, newer
parts have a slightly different argument which is log-base-2 of the
timeout.

Note that `i2c_set_timeout()` is a thin layer around `i2c_ll_set_tout()`
with the latter writing directly to the hardware register.  So the timeout
argument passed to `i2c_set_timeout()` needs to be in units calculated by
`i2c_ll_calculate_timeout_us_to_reg_val()`.
