Fix a couple drivers that do not correctly terminate their pci_device_id
lists. This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.

usbvision has a module parameter that ables the user to add a new USB
entry at driver load. This functionality is useless by experience
(adding statically the entry is easy).
Furthermore, the USB_DEVICE(0xfff0, 0xfff0) USB entry caused
usbvision_probe to be called for all unclaimed devices.

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.

- SYSFS: Replaced all to_video_device(cd), video_device_create_file,
video_device_remove_file and add the proper checks at create_file
- Converted old norm values to V4L2 ones.
- Robustness on sysfs hue/contrast/saturation queries.
Additional check in order to return 0 if the driver is not opened.
- Whitespace cleanups in usbvision-cards.c
This patch merges two fixes by Thierry MERLE and Mauro Chehab, and adds
