[PATCH 0/6] Qi power reduced boot and fixes

These patches do most of the Qi work for 500mW boot power limit, it allows
a GTA02 to boot without battery depending on VB_SYS performance (and I also
noticed it depended on absolute voltage level on battery V+ pin). One of the
changes is move to 200MHz for boot, not sure if that is actually needed yet.
There are some other fixes in there too. These will all be useful on GTA03
This should be most of the work for bootloader side, I noticed that totrst
seems to control if the kernel will power off apparently on this "8 seconds"
timeout, so there is more work to do on pcf50633 kernel driver around that
(and to understand the V+ level issue) before we can stay up reliably
without a battery.
We will also need to change the clock rate back to 400MHz in kernel side in early boot
and do the Cesar-style adjustments if we stick with 200MHz in bootloader.
