Patch #1 moves hardcoded vhub attributes (number of downstream ports and endpoints) to "struct ast_hub_config" which is then attached to "struct of_device_id". By doing this, it will be easier to enable ast2600 vhub which supports more ports and endpoints. Patch #2 enables AST2600 support in aspeed-vhub gadget driver. Patch #3 adds USB devices and according pin groups in aspeed-g6 dtsi.
