split uart2 initialization inside drv_uart. added receive data callback to use either with GPS or spektrum satellite
added spektrum satellite support, also freeing up 4 motor outputs for hexa/octo/camstab
configurable acc lpf and gyro lpf via cli
configurable (build-time) temperature lpf on baro. seems mostly useless.
fixed a nice boner bug in mag code which ended up multiplying magADC twice with magCal data.
fixed mpu3050 driver to allow configurable lpf, also broke other stuff in the process. considering moving this sort of stuff to "init" struct for sensor.
pwm driver rewritten to fully disable pwm/ppm inputs (such as using spektrum satellite case)
cleaned up double math in gps.c to use sinf/cosf etc
removed TRUSTED_ACCZ since its useless anyway
whitespace cleanup
