include: <io.h>: define (read|write)[bwlq]_relaxed
For Linux, It's always correct to substitute any of the read or
write _relaxed functions with their non relaxed counterpart.
Define functions that do this.
Unlike with Linux, they doesn't per se affect performance: barebox
writel doesn't imply memory barriers, instead it depends on
the architecture support to map IO memory regions as non-bufferable.
