0b8bd83cf3 [media] em28xx: don't sleep on disconnect
The DVB framework will try to power-down an adapter that no-one is using
any more, but this assumes that the adapter is still connected to the
machine. That's not always true for a USB adapter, so disable the sleep
operations when the adapter has been physically unplugged.

This prevents I2C write failures with error -19 from appearing
occasionally in the dmesg log.

0db4bf42ba [media] CXD2820R: Replace i2c message translation with repeater gate control
This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert
Schlabbach for identifying the register address and field to set.

The old i2c intercept code that prefixed messages with a passthrough byte has
been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been
updated appropriately.

Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities
could test it as well - from inspection I cannot see any problems.

This is patch v2. It fixes some schoolboy style errors and removes superfluous
i2c entries in cxd2820r.h.

e47b78f036 [media] cxd2820r: switch automatically between DVB-T and DVB-T2
Remove old DVB-T2 freq module param and detect DVB-T/T2 automatically.

Implementation is trial and error, if DVB-T does not lock try DVB-T2
and vice versa. That's done by replacing normal DVBFE_ALGO_SW with
DVBFE_ALGO_CUSTOM which gives better control for tuning process.

DVB-C still uses normal software ZigZag, DVBFE_ALGO_SW.
