d4862a87e3 i8254: fix out-of-bounds memory access in pit_ioport_read()
Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.

Fix this by ignoring read from the Mode/Command register.

This is CVE-2015-3214.

a15d09127b i8254: Convert PITCommonState to QOM realizefn
Instead of having the parent provide PITCommonClass::init,
let the children override DeviceClass::realize themselves.
This pushes the responsibility for saving and calling the parent's
realizefn to the children.
