BOARD_INDICATE_ARMED_STATE was only set during arming, so an external
component might have reset the board during param save, leading to param
loss.
This extends the API to trigger the arming state also while the shutdown
lock is taken.
Chip-select and SPI initialization uses the new config, whereas the drivers
still use the existing defines.
The configuration in board_config.h can be removed after all drivers are
updated.
Script to update include paths:
for i in $(grep -rl 'include <px4_work_queue' src platforms); do sed -i 's/#include <px4_work_queue/#include <px4_platform_common\/px4_work_queue/' $i; done
