First pass at InitDispBandwidth() for AVIVO chips

- support for LB allocation
- MC priority bumps for display1/2 on RV515 variants and RS690
If you are having display underflow problems (flickering on sides of
screen in high res modes, etc.) on RV515 or RS690 boards, try setting:
Option "DisplayPriority" "HIGH" in your config.
- still no support for full display watermark programming yet

Something similar might be useful in rhd as well.
