This patch adds tda998x specific parameters to allow it to be configured
for different boards using it. Also, this implements rudimentary audio
support for S/PDIF attached controllers.

The video-input-port (VIP) is highly configurable. This prepares
current driver to allow to configure VIP configuration, as some
boards connect lcd controller and TDA998x "pin-swapped" and depend
on VIP to swap the pins by register configuration.

The npix/nline registers are supposed to be programmed with the total
number of pixels/lines, not the displayed pixels/lines, and not minus
one either.

When switching between various drivers for this device, it's possible
that some critical registers are left containing values which affect
the device operation. One such case encountered is the VIP output
mux register. This defaults to 0x24 on powerup, but other drivers may
set this to 0x12. This results in incorrect colours.
Fix this by ensuring that the register is always set to the power on
default setting.

TDA19988 devices need their RAM enabled in order to read EDID
information. Add support for this.
