Do not limit I2C bus to 3 frequencies (100KHz, 400KHz, 1MHz). Instead
allow for any frequency up to 1MHz. Depending on the requested frequency
defined in clock-frequency DT entry, use the I2C spec data from either
Standard, Fast or Fast Plus mode.
This change removes use of rate IDs and use instead the rate value
itself as identifiers, allowing more flexible implementation.
Changes local variable clock_src in i2c_setup_timing() from uint32_t
to unsigned long for consistency.
