i2c: at91: Fix the functionality flags of the slave-only interface

Browse source 
[ Upstream commit d6d5645e5fc1233a7ba950de4a72981c394a2557 ]

When an I2C adapter acts only as a slave, it should not claim to
support I2C master capabilities.

Fixes: 9d3ca54b55 ("i2c: at91: added slave mode support")
