Details

This patch addresses the strange behaviour in the SVN SPI driver which caused it to hang occasionally. However, because the driver (still) isn't interrupt based, it's not really worth putting into SVN.

The main idea behind this patch was so that others can take a look at the PMU registers - some of which are displayed in the debug menu under port info - and contribute to the MC13783Regs wiki page[1].

The patch also adds a few things which I've determined such as powering the device off, and headphone detect logic (again, not interrupt based - though should be possible when we can catch external interrupts from the PMU).
