fsl: usb: make errata function common for PPC and ARM
This patch does the following things: 1. Makes the errata checking code common for PPC and ARM 2. Moves all these static inline functions into a dedicated C file Signed-off-by: Sriram Dash <sriram.dash@nxp.com> Signed-off-by: Rajesh Bhagat <rajesh.bhagat@nxp.com>
