I2C interface

The ATSAM BSP has I2C support, but i am slightly unclear about the API that
should be used to access it.

Using pread() & pwrite() seems to trigger assertions that look like memory
corruption in atsam_i2c_bus.c

The linux I2C userspace API seems to be suggested, which looks like
ioctrl(), but there is also a i2c_smbus_write_byte() type interface.
