to have both mappings (NC and WC) available so upper layer can decide
which to choose e.g. for SQs/QPs in some cases (Small Packets) and

Remove the global WC mapping of the total UARs since
UAR mapping should be decided per UAR (e.g we want
different mappings for EQs, CQs vs QPs).
We use ARCH_HAS_IOREMAP_WC to know if the current arch supports WC
(Write combining) IO memory mapping, if it is not supported
"uar->
