V4L/DVB (5517): Usbvision: store the device database more efficiently

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.
