alpha: fix ioread64be()/iowrite64be() helpers
Compile-testing the crypto/caam driver on alpha showed a pre-existing
problem on alpha with iowrite64be() missing:
ERROR: modpost: "iowrite64be" [drivers/crypto/caam/caam_jr.ko] undefined!
The prototypes were added a while ago when we started using asm-generic/io.h,
but the implementation was still missing. At some point the ioread64/iowrite64
helpers were added, but the big-endian versions are still missing, and
the generic version (using readq/writeq) is would not work here.
Change it to wrap ioread64()/iowrite64() instead.
Fixes: beba3771d9e0 ("crypto: caam: Make CRYPTO_DEV_FSL_CAAM dependent of COMPILE_TEST")
Fixes: e19d4ebc536d ("alpha: add full ioread64/iowrite64 implementation")
Fixes: 7e772dad9913 ("alpha: Use generic <asm-generic/io.h>")
Closes: https://lore.kernel.org/all/CAHk-=wgEyzSxTs467NDOVfBSzWvUS6ztcwhiy=M3xog==KBmTw@mail.gmail.com/
