This patch set is mainly to add board level usb support for mx6sxsabresd and
mx6slevk. Add pin mux settings and implement board_ehci_hcd_init and board_usb

Also in order to make the host port work for these two boards. A new weak
function is introduced. Detailed info about this is in the "usb:ehci-mx6
add board_usb_phy_mode function" patch commit log.

This patch set has already been tested on mx6sxsabresd and mx6slevk board.

Changes v3:
 Take Marek's suggestions, replace 'return val & USBPHY_CTRL_OTG_ID' with
 this new function like 'return board_usb_phy_mode(index);'
 Detailed discussion here:

Changes v2:
 Introduce a new weak function to let board have a choice to decide which mode
 to work at.
