parisc: Enable power button switch and add option to disable it
Due to a mismatch of memory mapping for PA2.0 with PSW.W=0,
the power button was broken on 64-bit machines.
The mapping bug is now fixed in qemu, so re-enable the button again.
Additionally add option to completely disable the power
switch with:
"-fw_cfg opt/power-button-enable,string=0"
