The mt2131 tuner reports lock even when the hardware should not
lock. This patch allows the s5h1409 demodulator to be configured to query
either the tuner driver for status, or the demodulator status when the
application requests lock status. This avoids returning false CARRIER
and/or SIGNAL lock status.

S5H1409 and MT2131 drivers.  This is the remainder of the changeset, which
only touches cx23885-dvb.c

The sram allocations for the cx23887 differ slightly from the cx23885.
This patch modifies the cx23887 specific sram memory map to reflect this.
As a result, interrupts and DMA handling have also been enabled in
cx23885_start_dma() for 887 specific boards.

ATSC streaming is now available on cx23885 and cx23887 bridges.

Break tuner.ko into separate modules. This was a quick change -
Tuner sub-drivers are still static-linked to tuner.ko, this will
change after using dvb_attach and removing the probing functions.

To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.

dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.

This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.

This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.

The tuner module has a rather aggressive range of possible i2c addresses.

As per the specs available, it appears as if there are no 4-byte tuners that
actually use i2c addresses in the range 0x64 thru 0x6f, yet, tuner-core claims
the address range 0x60 thru 0x6f.

Allowing tuner.ko to probe these addresses can cause potential damage to
certain IR receivers, RTC chips or any other IC's that might otherwise reside
on the i2c bus using one of these addresses.

The plan is to remove these i2c addresses from the i2c address range of the
tuner module. If any devices are discovered that actually do have tuners at
one of these addresses, the newer i2c probing methods will be used to handle
those cases.

In order to collect this information and avoid any potential regressions,
the following warning has been added upon successful detection of a tuner
using an i2c address in the range 0x64 thru 0x6f:

====================== WARNING! ======================
Support for tuners in i2c address range 0x64 thru 0x6f
will soon be dropped. This message indicates that your
hardware has a {tuner name} tuner at i2c address {addr}.
To ensure continued support for your device, please
send a copy of this message, along with full dmesg
output to v4l-dvb-maintainer@linuxtv.org
Please use subject line: "obsolete tuner i2c address."

There were a couple of places in the cx25840 initialization where the

Conform to this. Also move the ivtvfb.h header to include/linux: it is a
