[media] media: pci: constify stv0299_config structures

Declare stv0299_config structures as const as they are only passed as
an argument to the function dvb_attach. dvb_attach
calls its first argument on the rest of its arguments. The first
argument of dvb_attach in the changed cases is stv0299_attach and
the parameter of this function to which the object references are passed
is of type const. So, stv0299_config structures having this property
can be made const.

First line shows the file size before patching and second one shows size
after patching.
