This gets power consumption down under 1mA on the pad. Not really low
enough to sell, but I think this is about as low as the chip will go.

Products that want to remain usable (over USB) after a sensor failure
don't want to panic when the ms5607 fails, but products with limited
ROM space don't want to have extra code to check for the sensor
failure and panic. Change the MS5607 driver to allow either option,
and then make the micropeak based devices use it.

We have to erase the log before the flight starts, so this seems like
the latest possible moment.

This is the lowest power state we can reach, and consumes about 15µA
or less.

If we don't wait before measuring the battery, it will often read
under 3.2V right at boot time, which puts MicroPeak in flight mode
instead of USB mode.

No sense running the flight code when there's a USB cable attached.

This cleans up the build process for all architectures, providing a
common place to specify vpath, cflags and build rules for various
common files.

This driver uses the generic GPIO functions and allows per-LED port
and pin configuration. It supports up to 32 LEDs.
Rename SoC-specific LED drivers.
Remove enabled parameter to ao_led_init

The textram section must be aligned to 8 bytes to keep the linker
happy. However, if that section contains no data, the declaration will
set the __data_start__ value to that alignment, but the data section
itself would start on a 4-byte alignment, potentially 4 bytes lower
than the value indicated by __data_start__. This completely scrambles
initialized memory as the startup code will copy the data segment to
__data_start__, 4 bytes off of the actual data segment start.
Fix this by forcing the data segment to also be aligned to 8 bytes.

If you try this after the UART is running, it won't work.
