V4L/DVB (7464): Convert driver to use a single SRAM memory map
This reduces the memory footprint and removes the need to manually configure each map, which lead to a bug where the Fusion EXP 5 board broke for a while. This also fixes digital support again for the DViCO FusionHDTV5Express. Signed-off-by: Steven Toth <stoth@hauppauge.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
