io: change writeX_relaxed() to remove barriers
...
Now that we hardened writeX() API in asm-generic version, writeX_relaxed()
API is violating the rules when writeX_relaxed() == writeX() in the default
implementation.
The relaxed API shouldn't have any barriers in it and it doesn't provide
any ordering with respect to the memory transactions. The only requirement
is for writes to be ordered with respect to each other. This is achieved
by the volatile in the __raw_writeX() API.
Open code the relaxed API and remove any barriers in it.
