firedtv: rename variables and functions from firesat to firedtv
Signed-off-by: Rambaldi <Rambaldi@xs4all.nl>
Additional changes by Stefan Richter:
Renamed struct firedtv *firedtv to struct firedtv *fdtv and
firedtv_foo_bar() to fdtv_foo_bar() for brevity.

firedtv: rename files from firesat to firedtv
Signed-off-by: Rambaldi <Rambaldi@xs4all.nl>
Additional changes by Stefan Richter:
Name the directory "firewire" instead of "firedtv".
Standardize on "-" instead of "_" in file names, because that's what
drivers/firewire/ and drivers/media/dvb/dvb-usb/ use too.
Build fix.
