i2c: fsl_i2c: Migrate to Kconfig
- As there are no boards that use different values for speed / slave on
different buses, use a single option.
- Switch to using the common SYS_I2C_SPEED / SYS_I2C_SLAVE options.
- Introduce _HAS_ options for additional buses as only the first one is
common to all users.
- Convert all remaining symbols to Kconfig.
