driver/i2c/mxc: Enable I2C bus 3 and 4



Some SoCs have more than two I2C busses. Instead of adding ifdef
to the driver, macros are put into board header file where
CONFIG_SYS_I2C_MXC is defined.

- define slave for bus 3 with CONFIG_SYS_MXC_I2C3_SLAVE
If those defines are not set, default value is 100000
for speed, and 0 for slave.
- enable bus 3 with CONFIG_SYS_I2C_MXC_I2C3
