7edb3da: (USB: EHCI: make ehci-s5p a separate driver) raised an issue with ehci-s5p's driver data. Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd' and s5p_ehci is nothing but a pointer to hcd->priv; add hcd to the driver data rather than s5p_ehci. This fixes issues with null pointer dereferencing in s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().
