southbridge/hudson: Use MMIO instead of PIO to access PM space
The MMIO region is set up by AGESA very early on, so we can use it to access the PM register space in ramstage. 16-bit accessors are also provided to simplify some setup tasks. 16-bit accesses are not possible via PIO. The pm2_iowrite/read accessors are removed, as they are not used.
