i2c/drivers/generic: Add support for including a CDM

Chip Direct Mapping is exclusive to Windows; it allows specifying the
position where a chip is mounted. There are 8 positions and a _CDM
method should return 0xabcd0X, where X is the position.

Tested by booting Windows 11 on the StarLite Mk V, rotating the device
and checking the orientation is correct, where previously, it was
inverted.
