soc: fsl: qe: introduce qe_io{read,write}* wrappers

Browse Source 
The QUICC engine drivers use the powerpc-specific out_be32() etc. In
order to allow those drivers to build for other architectures, those
must be replaced by iowrite32be(). However, on powerpc, out_be32() is
a simple inline function while iowrite32be() is out-of-line. So in
order not to introduce a performance regression on powerpc when making
the drivers work on other architectures, introduce qe_io* helpers.

Also define the qe_{clr,set,clrset}bits* helpers in terms of these new
macros.
