[media] move the dvb/frontends to drivers/media/dvb-frontends
Raise the DVB frontends one level up, as the intention is to remove the drivers/media/dvb directory. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

- * For DVB-S high byte probably represents FEC
- * and low byte selects the modulator. The high
