Subject: [PATCH v4 47/47] soc: fsl: qe: remove PPC32 dependency from
CONFIG_QUICC_ENGINE

There are also ARM and ARM64 based SOCs with a QUICC Engine, and the core
QE code as well as net/wan/fsl_ucc_hdlc and tty/serial/ucc_uart has now been
modified to not rely on ppcisms.

So extend the architectures that can select QUICC_ENGINE, and add the rather
modest requirements of OF && HAS_IOMEM.

The core code as well as the ucc_uart driver has been tested on an LS1021A
(arm), and it has also been tested that the QE code still works on an mpc8309
(ppc).
