[PATCH] i2c: scx200_acb: add depends on HAS_IOPORT

[Randy Dunlap]

The scx200_acb driver uses inb()/outb() without depending on HAS_IOPORT,
which leads to build errors since kernel v6.13-rc1:
commit 6f043e757445 ("asm-generic/io.h: Remove I/O port accessors
for HAS_IOPORT=n")

Add the HAS_IOPORT dependency to prevent the build errors.

(Found in ARCH=um allmodconfig builds)
