GCS/SparkyBGC: updates to the board plugin

Added image of the Sparky BGC board and query the maximum gyro
range.
SparkyBGC: remove code for MPU 6050

Conflicts:
	flight/targets/sparkybgc/fw/pios_board.c
SparkyBGC: remove reference to MS5611
SparkyBGC: remove ADC code

These pins are no longer broken out and it was breaking
the PWM outputs.
SparkyBGC: remove references to main port
SparkyBGC: add HwSparkyBGC uavobject settings

This gives the BGC board a custom setting. Now that it has
different ports than Sparky this is appropriate.
SparkyBGC: update copyrights
Modueles/Brushless: fix typo
