Not all tvp5150 variants support the same, for example some have an
internal signal generator that can output a black screen.
So the device id and rom version have to be stored in the driver's
state to know what variant is a given device.
While being there, remove some redundant comments about the device
version since there is already calls to v4l2_info() with that info.

This is a partial revert of commit ed8d1cf07cb16d ("[media] Export I2C
module alias information in missing drivers") that exported the module
aliases for the I2C drivers that were missing to make autoload to work.
But there is a bug report [0] that auto load of the ir-kbd-i2c driver
cause the Hauppauge HD-PVR driver to not behave correctly.
This is a hdpvr latent bug that was just exposed by ir-kbd-i2c module
autoloading working and will also happen if the I2C driver is built-in
or a user calls modprobe to load the module and register the driver.
But there is a regression experimented by users so until the real bug
is fixed, let's not export the module alias for the ir-kbd-i2c driver
even when this just masks the actual issue.

The ov2659 driver performs device detection and initialization in the
following way:
- send reset command REG_SOFTWARE_RESET
- load array of predefined register's setting (~150 values)
- read device version REG_SC_CHIP_ID_H/REG_SC_CHIP_ID_L
- check version and exit if invalid.
As result, for not connected device there will be >~150 i2c transactions
executed before device version checking and exit (there are no
failures detected because ov2659 declared as I2C_CLIENT_SCCB and NACKs
are ignored in this case).
Let's fix that by checking the chip version first and start
initialization only if it's supported.

changeset 460b6c0831cb ("tvp5150: Add s_stream subdev operation
support") broke for em28xx-based devices with uses tvp5150. On those
devices, touching the TVP5150_MISC_CTL register causes em28xx to stop
streaming.
I suspect that it uses the 27 MHz clock provided by tvp5150 to feed
em28xx. So, change the logic to do nothing on s_stream if the tvp5150 is
not set up to work with V4L2_MBUS_PARALLEL.

After power-up, the tvp5150 decoder is in a unknown state until the
RESETB pin is driven LOW which reset all the registers and restarts
the chip's internal state machine.
The init sequence has some timing constraints and the RESETB signal
can only be used if the PDN (Power-down) pin is first released.
So, the initialization sequence is as follows:
1- PDN (active-low) is driven HIGH so the chip is power-up
2- A 20 ms delay is needed before sending a RESETB (active-low) signal.
3- The RESETB pulse duration is 500 ns.
4- A 200 us delay is needed for the I2C client to be active after reset.
This patch used as a reference the logic in the IGEPv2 board file from
the ISEE 2.6.37 vendor tree.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.
