drm/ast: Support multiple outputs
Systems with AST graphics can have multiple output; typically VGA
plus some other port. Record detected output chips in a bitmask and
initialize each output on its own.
Assume a VGA output by default and use SIL164 and DP501 if available.
For ASTDP assume that it can run in parallel with VGA.
Tested on AST2100.
v3:
* define a macro for each BIT(ast_tx_chip) (Patrik)
v2:
* make VGA/SIL164/DP501 mutually exclusive
