ADC: on channel overflow we should not zero last_ch6_micros
...
this happens every 64 seconds because of unused channels on the
ADC. Zeroing this creates a bad delta_t value for the DCM code.

Removed Gyro filter, In the end it doesn't help and I think it could actually hurt gyro integration.

ADC: added an enable_channel() API

ADC: only read channels that are actually being used
...
on the APM2 we usually use none of the ADC channels, although we may
use the airspeed sensor. This change means we detect which channels
are being read, and only do the SPI transfers for those ones. That
saves us about 100usec per timer interrupt (ie. about 10% of our CPU)

ADC: re-work for ADC code for full resolution and accurate timing

this changes the ADC code to return the full resolution of the
sensors. It also adds a new Ch6() interface that returns 6 channels at
once, so the IMU can read 3 accelerometers and 3 gyros at once, and
get the exact time that the values were accumulated over
