io/i2c: add support 10-bit addresses

10-bit addresses can range from 0 to (1111111111)2. That's why we need
to know in advance if the user is working with a 10-bit addressed
device.

The kernel driver also provides an ioctl function to enable the 10-bit
mode before setting the address globally on the device. Devfs enables
10-bit mode if it is required.
