usb: misc: sisusbvga: Move static const tables out to different include file

sisusb_init.h is included by multiple source files, but the big data
tables contained are only referenced by one of them, leaving the tables
'defined but not used' by the remainder. We have a choice to either
place them inside the source file, taking up may lines and potentially
overwhelming the source file OR tuck them away neatly inside their own
headerfile. The latter was chosen.

Fixes the following W=1 kernel build warning(s):
