[media] v4l: rcar-fcp: Fix module autoload for OF registration

Browse source 
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/media/platform/rcar-fcp.ko | grep alias
alias:          rcar-fcp

After this patch:

$ modinfo drivers/media/platform/rcar-fcp.ko | grep alias
alias:          rcar-fcp
alias:          of:N*T*Crenesas,fcpvC*
alias:          of:N*T*Crenesas,fcpv
alias:          of:N*T*Crenesas,fcpfC*
alias:          of:N*T*Crenesas,fcpf
