[PATCH 4/4] i2c: digicolor: Fix module autoload

[javier@osg.samsung.com (Javier Martinez Canillas)]

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/i2c/busses/i2c-digicolor.ko | grep alias
$

After this patch:

$ modinfo drivers/i2c/busses/i2c-digicolor.ko | grep alias
alias:          of:N*T*Ccnxt,cx92755-i2cC*
alias:          of:N*T*Ccnxt,cx92755-i2c
