Subject[PATCH 2/2] parisc: use the asm-generic version for readX()
parisc architecture seems to be mapping readX() and readX_relaxed() APIs
to __raw_readX() API.

__raw_readX() API doesn't provide any kind of ordering guarantees.
commit 032d59e1cde9 ("io: define stronger ordering for the default readX()
implementation") changed asm-generic implementation to use a more
conservative approach towards the readX() API.

Drop the arch specific version and rely on the asm-generic version for
parisc since it doesn't seem to do anything special with these macros.
