[POWERPC] QE: Add support for Freescale QUICCEngine UART
Add support for UART serial ports using a Freescale QUICCEngine. Update
booting-without-of.txt to define new properties for a QE UART node. Update
the MPC8323E-MDS device tree to add UCC5 as a UART. Update the QE library
to support slow UCC devices and modules.
