DVB: digitv: open nxt6000 i2c_gate for TDED4 tuner handling
dvb-pll normally opens the i2c gate before attempting to communicate with
the pll, but the code for this device is not using dvb-pll. This should
be cleaned up in the future, but for now, just open the i2c gate at the
appropriate place in order to fix this driver bug.

dvbdev: fix illegal re-usage of fileoperations struct
Arjan van de Ven <email address hidden> reported an illegal re-usage of
the fileoperations struct if more than one dvb device (e.g. frontend) is
present.
This patch fixes this issue.
It allocates a new fileoperations struct each time a device is
registered and copies the default template fileops.
Different chipsets have different amount of ram buffer (some have none),
so need to make sure that driver does proper setup for all cases from 0 on
to 48K, in units of 1K.
This is a backport of the code from 2.6.19 or later
When using netconsole, it is possible for the driver to try and
free skb's with IRQ's disabled. This could cause problems if the skb
had a destructor function that didn't expect this. The documented semantics
is that skb->destructor callback happens in softirq.
This driver uses port 0 to handle receives on both ports. So
the netif_poll_disable call in dev_close would end up stopping the
second port on dual port cards.
