SPDIF receiver needs to be on +3V14(STBY) supply
because it shares an I2C control bus with other parts
on +3V14(STBY) - namely the display board.
Hold SPDIF receiver in reset when in standby to
minimise current draw.

Sets base address to:
Pin 7 - SDIN/HWMODE needs to be pulled up 0111010x
during device reset to put the device into x: 0=read / 1=write
software control mode on un-reset. However
the I2C_SDA line already has a pullup
elsewhere (by IC300) so one is not needed
here.
