USB: sisusbvga: remove console support 

It was marked as BROKEN since commit 862ee699 (USB: sisusbvga: Make
console support depend on BROKEN) 2 years ago. Since noone stepped up to
fix it, remove it completely.

Net2280 and a SiS315 chip.

To compile this driver as a module, choose M here; the module will be
called sisusbvga. If unsure, say N.
config USB_SISUSBVGA_CON
bool "Text console and mode switching support" if USB_SISUSBVGA
depends on VT && BROKEN
select FONT_8x16
help
Say Y here if you want a VGA text console via the USB dongle or
want to support userland applications that utilize the driver's
display mode switching capabilities.
Note that this console supports VGA/EGA text mode only.
By default, the console part of the driver will not kick in when
the driver is initialized. If you want the driver to take over
one or more of the consoles, you need to specify the number of
the first and last consoles (starting at 1) as driver parameters.
For example, if the driver is compiled as a module:
modprobe sisusbvga first=1 last=5
If you use hotplug, add this to your modutils config files with
the "options" keyword, such as eg.
options sisusbvga first=1 last=5
If the driver is compiled into the kernel image, the parameters
must be given in the kernel command like, such as
sisusbvga.first=1 sisusbvga.last=5
