OMAP5: I2C: Set I2C_BUS_MAX to 5 to enable I2C4 and I2C5

I2C4 and I2C5 are utilized on all known OMAP5 hardware platforms.
In order to be able to select one of these buses however, I2C_BUS_MAX
has to be set to 5; do this here.

Please note that for working bus selection, a fix to the i2c driver
is required as well (subject of a separate patch).
