hw/rtc: Refactor trap handlers
With the planned retirement of the special ioport emulation code, we
need to provide emulation functions compatible with the MMIO prototype.
Merge the two different trap handlers into one function, checking for
read/write and data/index register inside.
Adjust the trap handlers to use that new function, and provide shims to
implement the old ioport interface, for now.
