On the JH7110 the reset registers don't get their own memory range, but instead follow the clock control registers. The registers still follow the same structure though, so let's factor out the common code to handle all these cases.

This works because there are an even number of assert and status registers, so they're only ever accessed in pairs on 64bit boundaries. There are however other reset controllers for audio and video on the JH7100 SoC with only one status register that isn't 64bit aligned so 64bit I/O results in an unaligned access exception. Switch to 32bit I/O in preparation for supporting these resets too.
