V4L/DVB: lgs8gxx: remove firmware for lgs8g75
The recently added support for lgs8g75 included some 8051 machine code without accompanying source code. Replace this with use of the firmware loader. Compile-tested only. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
