media: ngene: use common DVB I2C client handling helpers
Like in ddbridge, get rid of all duplicated I2C client handling constructs and rather make use of the newly added dvb_module_*() helpers. Makes things more clean and removes the (cosmetic) need for some variables. The check on a valid ptr on ci->en isn't really needed since the cxd2099 driver will set it at a time where it is going to return successfully from probing.
