[PATCH] media: au0828: add support for Monoprice 106456 USB ATSC/QAM tuner

[Joseph Breihan via B4 Relay]

From: Joseph Breihan <linux@xxxxxxxxxxxxxxxxx>

The Monoprice 106456 (board rev TV22AD-A, also sold as the AnyTV
AUTV002) is a USB ATSC/QAM tuner that enumerates as 05e1:0400 and
reports itself as a "Syntek Semiconductor USB 2.0 Video Capture
Controller". The hardware is an Auvitek AU0828A bridge with an AU8522
demodulator and an NXP TDA18271HDC2 tuner at I2C address 0x60 -- the
same demod/tuner combination as the existing Hauppauge Woodbury board.

Adds board profile and the USB ID so the device binds. The digital
frontend is electrically identical to the Woodbury, so share that
board's au8522/tda18271 configuration and attach path rather than
duplicating it. Tested with over-the-air 8VSB ATSC: it locks and
streams a live 720p transport stream.

Some 05e1:0400 units reportedly ship a Microtune MT2131 tuner with an
AU8502 demodulator instead. This patch does not handle that variant,
but it can't regress it either: 05e1:0400 matches no driver today, and
on the MT2131 units tda18271_attach() just fails, so no frontend is
registered.
