media: dvb: represent min/max/step/tolerance freqs in Hz

Right now, satellite frontend drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.

However, the main problem is that universal frontends capable
of handling both satellite and non-satelite delivery systems
are appearing. We end by needing to hack the drivers in
order to support such hybrid frontends.

So, convert everything to specify frontend frequencies in Hz.

[media] dvb_frontend: pass the props cache to get_frontend() as arg

Instead of using the DTV properties cache directly, pass the get
frontend data as an argument. For now, everything should remain
the same, but the next patch will prevent get_frontend to
affect the global cache.

This is needed because several drivers don't care enough to only
change the properties if locked. Due to that, calling
G_PROPERTY before locking on those drivers will make them to
never lock. Ok, those drivers are crap and should never be
merged like that, but the core should not rely that the drivers
would be doing the right thing.

[media] dvb: Get rid of typedev usage for enums

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.
