Before dvb_pll_attch call, be sure that drxd demodulator was
initialized, otherwise, dvb_pll_attach() will always failed.
In dvb_pll_attach(), first thing done is to enable the I2C gate
control in order to probe the pll by performing a read access.
As demodulator was not initialized, every i2c access failed.
