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).
