The code was testing an 8-bit address against a 7-bit address.  Will the
confusion of the two never cease?
Biggest flaw of the I2C protocol:  the R/W bit is the LSB instead of the
MSB.  No one can ever agree if addresses are 7-bits and the R/W bit
follows them, or if they are 8-bit and the R/W bit is OR-ed into the
address byte.  If the R/W bit was first, it wouldn't make any difference!

I got strange message when I did modprobe bt878:
bt878_probe: card id=[0x0],[ <NULL> ] has DVB functions.
The card_list array is terminated by sentinel entry.
But this list is traversed by:
for (i = 0, dvb_cards = card_list; i < ARRAY_SIZE(card_list);
     i++, dvb_cards++) {
...
}
in bt878_probe().
So this loop checks dummy sentinel entry, too.
This patch removes unnecessary sentinel entry.

One bit wide bitfields need to declared unsigned to have the range 0 to
1, or they have the range -1 to 0.

A few techniques to reduce the driver's size by about 1700 bytes on ia32,
probably more on x86-64.

Put the biggest fields first, less padding is necessary that way.

Put fields with a limited range into a smaller type.  For example
VideoChannels will fit in 3 bits, and TunerType can use 8 bits.

Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but
they can't just go into an 8-bit field with no changes, since -1 was used
as a flag to indicate a value was not present.  So what we do is create a
one-bit flag for each one to indicate if a value is or is not present.

This only takes 9 bits and has the added advantage that when the register
isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the
structure definition since the default value for the flag will be zero.

Changed usbvision cards table to allow:
	1) Not repeat USB ID on two structs;
	2) Not need to specify both usb and card description tables at
	   the same order, removing some magic;
Some cards had duplicated names. Fixed.
A test for an specific board were doing by using a string comparation.
The comparation were wrong. Also, it is not a good practice to recognize
a board based on his string name.

There were many places in the driver which had long sequences of constant
register initializations.  These were done with one function call per
register.  The register address and value were immediate values in the
function calls.
This is very inefficient, as each register and value take twice the space
when they are code, as each includes a push instruction to put it on
the stack.  There there is the overhead, both size and time, for a
function call for each register.  It's also quite a few lines of C code
to do this.
The patch creates a function that writes multiple registers from a list,
and a macro that makes it easy to construct a such a list as a const
static local to send to the function.
This gets rid of quite a bit of C code, and shrinks the driver by around
8k, while at the same time being more efficient.

there were several "magic" for loops, addressing gpiomux array size (4).
Adrian Bunk showed that one of the loops were wrong, going from 0 to 4.

This patch provides the right fix for this trouble, by using ARRAY_SIZE
on all places where we have a for loop using gpiomux.
