Thomas Zimmermann 477277c7fd 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
