ralink_halt() does nothing that machine_halt() doesn't already do, so it
adds no value.
It actually causes incorrect behaviour due to the "unreachable()" at the
end. This tells the compiler that the end of the function will never be
reached, which isn't true. The compiler responds by not adding a
'return' instruction, so control simply moves on to whatever bytes come
afterwards in memory. In my tested, that was the ralink_restart()
function. This means that an attempt to 'halt' the machine would
actually cause a reboot.
So remove ralink_halt() so that a 'halt' really does halt.

The old address is no longer valid. Use the my new one instead.

The reset_ops structure is never modified. Make it const.

Setting pm_power_off is apprently wrong and makes drivers such as
gpio-poweroff not work.

Resetting these SoCs requires no real magic. The code is straight forward.
