[PATCH] usb: ehci-s5p: fix: Fix null pointer dereferencing

7edb3da makes ehci-s5p as a separate driver. But,
it raised an issue with its 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().
