[media] media: Change media device link_notify behaviour
Currently the media device link_notify callback is invoked before the
actual change of state of a link when the link is being enabled, and
after the actual change of state when the link is being disabled.
This doesn't allow a media device driver to perform any operations
on a full graph before a link is disabled, as well as performing
any tasks on a modified graph right after a link's state is changed.
This patch modifies signature of the link_notify callback. This
callback is now called always before and after a link's state change.
To distinguish the notifications a 'notification' argument is added
to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates
notification before link's state change and
MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after
link flags change.

[media] stb0899: store autodetected inversion while tuning in non S2 mode
In non S2 mode, the device is able to autodetect inversion. So
let's store it for tuning to S2 transponders.

[media] stb0899: allow minimum symbol rate of 2000000
Looks like product datasheets for tuners containing STB0899 are
suggesting specification for min. symbol rate of 2MS/s.
Some specs found here, all suggesting 2MS/s for min. symbol rate:
Comtech DVBS2-6899

TechniSat SkyStar HD2

Azurewave AD-SP400
http://www.pulsat.com/products/AzureWave-AD%252dSP400-High-Definition-PC-Card.html
New patch:
This makes minimum symbol rate driver capabilities on par with some
accessible datasheet specifications*, and allows tuning on linux to
transponders that have symbol rate between 2000000-5000000, too.
Patch was tested successfully on Eutelsat 16A transponders that
became reachable with it (2000000 < symbol rate < 5000000):

[media] stb0899: fix inversion enum values to match usage with CFR
Throughout the zig-zag-implementations, inversion is taken into
account when reading and writing the CFR register, which contains
the derotator frequency. As swapping IQ signals changes the sign
of that register for example, the idea is to compensate that sign
change by multiplying the register value with the inversion enum
value.
The current enum values 0 and 1 for IQ_SWAP_OFF and IQ_SWAP_ON
don't work in the case IQ_SWAP_OFF, due to the multiplication by
zero (I've only found a single device which actually uses
IQ_SWAP_OFF in it's config).
I've changed the enum values to +1 and -1 to accommodate to the
intended usage.

[media] stb0899: enable auto inversion handling unconditionally
It seems that current inversion handling addresses only the signal
routing on the PCB, i. e. IQ signals are either swapped or not.
But when the device is operated in a Satellite Channel Router (SCR)
environment, an additional inversion is required due to the way how
the SCR works. Therefore it makes sense to me to always enable auto
inversion handling and drop the enum value IQ_SWAP_AUTO.
