Input: fsl-imx25-tcq - fix module autoload when registered via OF 

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/input/touchscreen/fsl-imx25-tcq.ko | grep alias

After this patch:

$ modinfo drivers/input/touchscreen/fsl-imx25-tcq.ko | grep alias
alias:          of:N*T*Cfsl,imx25-tcqC*
alias:          of:N*T*Cfsl,imx25-tcq
