[PATCH 6/6] qi-add-totrst-clear-before-linux.patch

[Andy Green]

Before leaving for Linux, gratuitously clear down the totrst / timeout counter
to help stop us dying partway through boot on effective power-off.

In the case we have no battery or battery < ~3V, we still somehow need to do
more in kernel because it can switch itself off more than 8 seconds
after this point.
