Subject: V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug
 enabled

set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't
reported.

This patch changed set_addr printk to print a message only if set_addr is
wrong.

It also fix printk at set_type, since, if an attach were failing, nothing
were reported.

With the current code, working or not, a call to set_addr will produce a debug
printk.

also, set_type() were producing a false error message on tuner_xc2028, since
it were requesting for setting a frequency on a place where firmware name
weren't set yet.

Subject: V4L/DVB (7750): au0828/ cleanups and fixes

This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
  renamed it to "au0828_debug"
  this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
  already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static
