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().
