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.

The scanning itself just fails (as before this series) but now
the correct busses are scanned.

I2C bus 1 has internally a switch. Use it as I2C_1_MUX_1 and
I2C_1_MUX_3, letting the I2C core handling the switch.

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.
