parisc: Drop homebrewn io[read|write]64_[lo_hi|hi_lo]
The parisc implements ioread64_lo_hi(), ioread64_hi_lo() iowrite64_lo_hi() and iowrite64_hi_lo() while we already have a perfectly working generic version in the generic portable assembly in <linux/io-64-nonatomic-hi-lo.h>. Drop the custom versions in favor for the defaults. Fixes: 77bfc8bdb5a1 ("parisc: Remove 64bit access on 32bit machines") Cc: Arnd Bergmann <arnd@arndb.de> Acked-by: Helge Deller <deller@gmx.de> Reported-by: Helge Deller <deller@gmx.de> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
