net: mac8390 - Sort out memory/MMIO accesses and casts
commit 5c7fffd0e3b57cb63f50bbd710868f012d67654f ("drivers/net/mac8390.c: Remove useless memcpy casting") removed too many casts, introducing the following warnings: | drivers/net/mac8390.c:248: warning: passing argument 1 of '__builtin_memcpy' makes pointer from integer without a cast | drivers/net/mac8390.c:253: warning: passing argument 1 of 'word_memcpy_tocard' makes pointer from integer without a cast | drivers/net/mac8390.c:255: warning: passing argument 2 of 'word_memcpy_fromcard' makes pointer from integer without a cast Instead of just readding the casts, - move all casts inside word_memcpy_{to,from}card(), - replace an incorrect memcpy() by memcpy_toio(), - add memcmp_withio() as a wrapper around memcmp(), - replace an incorrect memcpy_toio() by memcpy_fromio().
