[media] dvb: remove dvb_frontend_parameters from calc_regs()
The calc_regs() callback is used by a few frontends (mt352, nxt200x, digitv and zl10353). On all places it is called, the parameters are set by DVBv5 way. So, just use the DVBv5 struct and remove the extra parameter. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
