media: i2c: adv748x: Export I2C device table entries as module aliases

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, and the driver is only exporting the OF ID
table entries as module aliases.

So if the driver is built as module, autoload won't work since udev/kmod
won't be able to match the registered OF device with its driver module.

Before this patch:

$ modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias
alias:          of:N*T*Cadi,adv7482C*
alias:          of:N*T*Cadi,adv7482
alias:          of:N*T*Cadi,adv7481C*
alias:          of:N*T*Cadi,adv7481

After this patch:

modinfo drivers/media/i2c/adv748x/adv748x.ko | grep alias
alias:          of:N*T*Cadi,adv7482C*
alias:          of:N*T*Cadi,adv7482
alias:          of:N*T*Cadi,adv7481C*
alias:          of:N*T*Cadi,adv7481
alias:          i2c:adv7482
alias:          i2c:adv7481
