Subject: [PATCH v2 1/1] i2c: add HAS_IOPORT dependencies
In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them.

Note: This patch does not depend any not-yet-mainline HAS_IOPORT changes
and may be merged via subsystem specific trees at your earliest
convenience.
v1 - v2:
- Removed HAS_IOPORT dependency for I2C_PARPORT
