ad020dc2fe [media] tuner-core: remove usage of DIGITAL_TV
tuner-core has no business to do with digital TV. So, don't use
T_DIGITAL_TV on it, as it has no code to distinguish between
them, and nobody fills T_DIGITAL_TV right.

2d351df443 [media] Remove the remaining usages for T_STANDBY
tda9887 used to use the T_STANDBY type internally, while tea5761
used it to put the device to sleep. Fix the code for it to work
properly with the tuner core changes and remove this flag from
tuner.h.

a34ec5f374 [media] tuner-core: dead code removal
Remove the now obsolete set_freq. Also merge set_addr and set_type_addr.

In the past, it used to have two different setup calls, one to set just
the tuner type to any tuner found, and another to set the type only if
the address matches. Those two internal calls were grouped together,
but the functions weren't merged, making the code uglier.

No functional changes are done in this patch.

900f734b3b [media] tuner-core: Don't use a static var for xc5000_cfg
A static var is evil, especially if a device has two boards with

cbde689823 [media] tuner-core: Better implement standby mode
In the past, T_STANDBY were used on devices with a separate radio tuner to
mark a tuner that were disabled. With the time, it got newer meanings.

Also, due to a bug at the logic, the driver might incorrectly return
T_STANDBY to userspace.

So, instead of keeping the abuse, just use a boolean for storing
such information.

We can't remove T_STANDBY yet, as this is used on two other drivers. A
latter patch will address its usage outside tuner-core.

9f3f71ef6d [media] tuner-core: Reorganize the functions internally
This is a big patch with no functional changes. It just
rearranges everything inside the driver, and prepares to
break TV and Radio into two separate fops groups.

Currently, it has an heuristics logic to determine if the
call came from radio or video. However, the caller driver
knows for sure, so tuner-core shouldn't try to guess it.

3f25ffa2cd [media] cx231xx: Use a generic check for TUNER_XC5000
The check for xc5000 assumes that the tuner will always
be using the same bus and will have the same address.
As those are configurable via dev->board, it should use,
instead, the values defined there.

Also, a similar type of test will be needed by other
tuners (for example, for TUNER_XC2028)
