usb: ehci-mxc: check for pdata before dereferencing

commit f375fc520d4df0cd9fcb570f33c103c6c0311f9e upstream.

Commit 7e8d5cd93fac ("USB: Add EHCI support for MX27 and MX31 based
boards") introduced code that could potentially lead to a NULL pointer
dereference on driver removal.

Fix this by checking for the value of pdata before dereferencing it.
