kernel/resource: Introduce request_mem_region_muxed()
Support for requesting muxed memory region is implemented but not
currently callable as a macro. Add the request muxed memory
region macro.
MMIO memory accesses can be synchronized using request_mem_region() which
is already available. This call will return failure if the resource is
busy. The 'muxed' version of this macro will handle a busy resource by
using a wait queue to retry until the resource is available.
