Add pinmux settings, implement board_ehci_hcd_init, board_usb_phy_mode
There are two usb port on mx6slevk board:
1. otg port
2. host port
The following are the connection between usb controller and board usb
interface, host port has not ID pin set:
otg1 core <---> board otg port
otg2 core <---> board host port
In order to make host port work, board_usb_phy_mode return 0 to let
ehci-mx6.c driver decide otg2 core to works in host mode.

This looks like an duplication. Aren't those bits defined somewhere in
generic code already ?
If this way 'int board_usb_phy_mode(int port, enum usb_init_type *type)'
can be accpeted, these bits are not needed and I'll move these bits in
the seperate PHY register struct access patch. Anyway, after the board
level usb support patch.
