tda18271: pass i2c gate configuration into tda18271_attach()
From: Michael Krufky <mkrufky@linuxtv.org>
If we pass TDA18271_GATE_DIGITAL into tda18271_attach(), it will always try to
use the digital demodulator's i2c gate.
If we pass TDA18271_GATE_ANALOG into tda18271_attach(), it will always try to
use the analog demodulator's i2c gate.
If we pass TDA18271_GATE_AUTO into tda18271_attach(), it will try to use the
analog demodulator's i2c gate when tuning in analog mode, and it will try to
use the digital demodulator's i2c gate when tuning in digital mode.
