[PATCH 2/5] net: mac8390: Use standard memcpy_{from,to}io()

[Geert Uytterhoeven]

The mac8390 driver defines its own variants of memcpy_fromio() and
memcpy_toio(), using similar implementations, but different function
signatures.

Remove the custom definitions of memcpy_fromio() and memcpy_toio(), and
adjust all callers to the standard signatures.

This is a dependency for "m68k: Move mem*io define guards to
<asm/kmap.h>".

Untested on real hardware, assembler output compared.
