AP_AHRS: choose the best accelerometer at each drift correction step
...
this greatly reduces the impact of aliasing on accelerometers by
choosing the accelerometer that produces the smallest error term in
DCM. The difference can be quite dramatic on the Pixhawk.

AP_AHRS: removed the AHRS_GPS_DELAY parameter
...
the best value has turned out to be 1, and tweaking it has not turned
out to be useful, so this simplifies the code in preparation for
adding the anti-aliasing handling with multiple accelerometers
