Add AST2600 support in aspeed-vhub driver. There are 3 major differences
between AST2500 and AST2600 vhub:
  - AST2600 supports 7 downstream ports while AST2500 supports 5.
  - AST2600 supports 21 generic endpoints while AST2500 supports 15.
  - EP0 data buffer's 8-byte DMA alignment restriction is removed from
    AST2600.
