Subject: iio: adc: imx25-gcq: Fix module autoload

[ Upstream commit 8f0d7daf53972da0004f7a5a4d938c85333db300 ]

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/iio/adc/fsl-imx25-gcq.ko | grep alias
$

After this patch:

$ modinfo drivers/iio/adc/fsl-imx25-gcq.ko | grep alias
alias:          of:N*T*Cfsl,imx25-gcqC*
alias:          of:N*T*Cfsl,imx25-gcq
