si2165_set_if_freq_shift() needs to call get_if_frequency() in order to do
the right shift. Add such logic inside the function, simplifying the logic
for the callers.

Datasheet says they must be rewritten after reset.
But it only makes sense to write them when trying to tune afterwards.

It is common the need of writing a table of values. Add a function to provide a
helper to address such case. This will allow further code cleanups.

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

In case of an error function si2165_upload_firmware() releases the already
requested firmware in the exit path. However, there is one deviation where
the function directly returns. Use the correct cleanup so that the firmware
memory gets freed correctly. Detected by Coverity CID 1269120.
