This updating of the driver setting is for EMI issue with GPS and FCC.
   With this setting the clock is sinusoidal

   N.B. sd_bench fails on SanDISK HC, but Passes SanDISK **HC1** and
   Kingston cards.

   ****Use HC1 or Kingston cards!***

   Testing done on SanDISK HC all failed sd_bench with Drive/Slew other
   than default and _PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE

	_PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE    Square noisy, pass SanDISK HC
        _PIN_OUTPUT_FAST|_PIN_OUTPUT_LOWDRIVE     Square noisy, pass SanDISK HC
        _PIN_OUTPUT_HIGHDRIVE|_PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1
        _PIN_OUTPUT_LOWDRIVE |_PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1
                              _PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1

_Stof, bsearch, param_find_changed

* added a parameter for enabled the smart battery
* start tel1 and tel2 at 921600 and max rate
* turned up the max tx rate on mavlink streams for telem1 and telem2
* turned off mavlink stream for tel1 in 4250_teal. This is connected to TX1 FTDI UART and has issues.
* moved check to 4250 board ID to start mpu9250s for Teal airframe into fmuv4 rc.board.

 - these flags were accumlating on top of each other anytime cmake had to reconfigure

   If the BOARD_HAS_CONTROL_STATUS_LEDS is set the status LED will
   not be PWM controlled.

   UI LED will always be PWM controlled.

 - fixes #10925
