mx6sxsasbresd board and mx6slevk board does not have board level support 
for usb. This patchset is mainly to add pinmux and implement 
board_ehci_hcd_init and board_echi_power and add USB CONFIG in header 
file to make usb work fine.

I'll send another patch for review, if "usb:ehci-mx6 add 
board_ehci_usb_mode function" is fine.
