[JFYI] removed deprecated usb_device.*_bcd properties

[Danny Kukawka]

Hi,

I've removed these deprecated keys from SPEC and from the Linux code tree 
(someone need to adapt the FreeBSD code) because they reached end of lifetime 
(2008-03-21):

* usb_device.speed_bcd (int) --> replacement: usb_device.speed (double)
* usb_device.version_bcd (int) --> replacement: usb_device.version (double)

Please note there is no backward compatibility via the existing 
01-deprecated-keys.fdi since there is no way to copy info from int (BCD2) to 
double via FDI files.

Cheers,

Danny
