[xsens700] Checked signs with real hardware.
[airframes] two times same, one not compiling
removed unused OVERRIDE_UARTx_IRQ_HANDLER
cleanup trailing whitespaces
[separate FBW-AP] Transfer RC-channels from radio.h, send COMMANDS and FBW_STATUS from the ap side.

closes #726
[intermcu_uart] Naming convention: PORT_NR=1 -> PORT=UART1
[link_mcu] replace _BV by bit_is_set
[Lisa/S] Renamed Lisa/S V0.1 to V1.0.

The boards are software compatible, and as probably more people will
have the V1.0 it will decrease confusion. Those that have V0.1 will much
more likely know that they can use V1.0 board file anyways. :)
[Lisa/S] Fixed comments in the lisa_s board file.
[Lisa/S] Fixed the battery voltage calculation.
[Lisa/S] Added diagram of the motor names and directions.
[Actuators] Added the possibility to change base timer frequency.

In case of the Lisa/S we have MOSFETs connected to the servo outputs.
This makes it possible to drive brushed motors directy. The default
servo actuator driver is using a 1MHz input to drive the counter compare
timer. This limits the maximum (reasonable) timer period frequency to
1KHz. This frequency is well in the hearing range resulting in a very
unpleasant high pitched sound produced by the motors.

This change makes it possible to drive the basic STM32F1 timer with
maximum of 36MHz and advanced timer with 72MHz making the maximum
(reasonable) timer period 36kHz and 72kHz respectively. This puts the
noise produced by the motors way beyond hearing range and making the
craft flight much more pleasant. :)

Beyond that it shuold make the operation of the motors more efficient as
the induction of the coils should smoothen the signal out. But that
would need additional measurement to be confirmed/rejected.
[Lisa/S] Added example Lisa/S V1.0 on Ladybird airframe file.
Merge pull request #730 from esden/lisa_s

Lisa/S V1.0 support and an option to change the base tick clock of the servo pwm driver
