[homematic] Some fixes and support for new device versions (#10438)

* Removed method that was already marked as deprecated

Signed-off-by: Martin Herbst <develop@mherbst.de>

* Handle HM-ES-TX-WM with firmware version >= 2.0 as different device

The device provides different data points (channels) depending on the
firmware version. Therefore devices with a firmware version >= 2.0 are
handled as a different device.

Fixes #9793

* Don't change uninitialized thing state automatically to online

* Listen to all network interfaces instead of limiting it to only one

This also makes the specification of a separate bind address
superfluous.

Fixes #9855

Fixes #10075

* Add support for HmIP-eTRV-C-2 device

The event messages received for this device are not correctly formatted
and thus some special treatment for at least one data point is required.
