The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's
i2c implementation where it did not properly support a single i2c read request
(sending it as an i2c write request instead).  Version 1.20 of the firmware
added support for a new i2c API which supported such requests.

This change defaults to fw 1.20 for all devices, but does not default to using
the new i2c API (since initial testing suggests problems interacting with the
mt2060).  Maintainers can enable the use of the new i2c API by putting
the following into their frontend initialization:

struct dib0700_state *st = adap->dev->priv;
st->fw_use_new_i2c_api = 1;

Also note that the code expects i2c repeated start to be supported.  If the
i2c slave does not support repeated start, i2c messsages should have the
I2C_M_NOSTART flag set.

Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new
firmware fixing the issue as well as example i2c code utilizing the interface.

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.

Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.

options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.

With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

This patch enables support for repeating last event when a key is holded
down with dib0700 devices. It works with rc5 and nec remotes.
It also fixes an annoying bug that floods kernel log with "Unknown key"
messages after each keypress. This happened because the driver was not
resetting infrared register after each poll so it kept polling last key
even if nothing was being pressed. Fixing this, (calling rc_setup after
each poll), permits to implement key repeat.

The new firmware returns the data of the REQUEST_POLL_RC request in
reversed order. The default is RC5, but it can be adjusted using a
module parameter.

When trying to use a Hauppauge Nova-T Stick on a big-endian architecture
(such as powerpc) no frontend can be attached.
The attached patch fixes this problem by removing two lines in
dib0700_ctrl_rd() that try to correct the endianess on two values that
already are correct:
-       /* think about swapping here */
-       value = le16_to_cpu(value);
-       index = le16_to_cpu(index);
With this simple patch this dvb hardware works great, thanks to anyone
involved for the good work. :)

This changeset finalizes the support of the Hauppauge Nova-T 500 (Dual DVB-T).
It adds correct AGC setting for the 3000P, correct firmware download state
detection.
Additionally it fixes the mt2060-driver to be able to be used with dvb_attach.

Added module for DiB0700 based USB devices. This module is preliminary and
untested (because of a lack of test devices) but should work.
Further commits will be necessary to make it work properly.
