arm(64): Manually clean up the mess left by write32() transition
This patch is a manual cleanup of all the rubble left by coccinelle waltzing through our code base. It's generally not very good with line breaks and sometimes even eats comments, so this patch is my best attempt at putting it all back together. Also finally remove those hated writel()-style macros from the headers.
