Unfortunately, on devices that have multiple interfaces, udev->dev
points to the parent device (usb) instead of the cx231xx specific one.
Due to that the logs don't look too nice, as they'll print messages
as if they were produced by USB core:
usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces
Instead of using the name of the parent device, let's use the name
of the first cx231xx interface for all cx231xx sub-modules.
With this path, the logs will be nicer:
cx231xx 1-2:1.1: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces

Don't need to show when it starts or stops. Just print lines
when devices are found.
After the changes, the output for i2c scan will be like:
usb 1-2: i2c scan: found device @ port 0 addr 0x40 [???]
usb 1-2: i2c scan: found device @ port 0 addr 0x60 [colibri]
usb 1-2: i2c scan: found device @ port 0 addr 0x88 [hammerhead]
usb 1-2: i2c scan: found device @ port 0 addr 0x98 [???]
usb 1-2: i2c scan: found device @ port 3 addr 0xa0 [eeprom]
usb 1-2: i2c scan: found device @ port 2 addr 0x60 [colibri]
usb 1-2: i2c scan: found device @ port 2 addr 0xc0 [tuner]
usb 1-2: i2c scan: found device @ port 4 addr 0x20 [demod]

I2C address 0x10 is the demod. While here, make the array const.

Otherwise, it would produce lots of useless messages like:
cx231xx: cx231xx_send_usb_command: failed with status --32
After this patch, I2C scan will produce an useful report:
[ 9494.050807] cx231xx: i2c_scan: checking for I2C devices on port=0 ..
[ 9494.074928] cx231xx: i2c scan: Completed Checking for I2C devices on port=0.

Now cx231xx_i2c_check_for_device works like i2c_check_for_device of em28xx driver.
For me this fixes scanning of all ports but port 2.

There are lots of debug printks printed with pr_info. Also, the
printk's data are not too coherent:
- there are duplicated driver name at the print format;
- function name format string differs from function to function;
- long strings broken into multiple lines;
- some printks just produce ugly reports, being almost useless
as-is.
Do a cleanup on that.
Still, there are much to be done in order to do a better printk
job on this driver, but, at least it will now be a way less
verbose, if debug printks are disabled, and some logs might
actually be useful.

It currently does just like what pr_foo() macros do. So,
replace them.
A deeper cleanup is needed, as there are lots of debug macros
printed with pr_info.

This is a preparation for mapping I2C_1_MUX_1 and I2C_1_MUX_3 later to the seperate
muxed i2c adapters.
Map mux adapters to I2C_1 for now.
Add local variables for i2c_adapters in dvb_init to get line lengths
shorter.

Instead of using the same name for all 3 i2c physical buses
inside cx231xx, name them differently, adding a number
to it. This helps to better deal with the logs.

Do not shift the already 7bit i2c address.
Print a message also for write+read transactions.
For write+read, print the read buffer correctly instead of using the write
buffer.
