Implement switching of the debug registers. While the number of registers is massive, CPUs usually don't implement them all (A57 has 6 breakpoints and 4 watchpoints, which gives us a total of 22 registers "only"). Also, we only save/restore them when MDSCR_EL1 has debug enabled, or when we've flagged the debug registers as dirty. It means that most of the time, we only save/restore MDSCR_EL1.
