[boards] add missing defines for lisa/l board
[rotorcraft] fix stabilization_attitude_read_rc_setpoint_eulers

Reported by Ewoud.
The constants max_phi_scale etc. were zero because it is an integer divide
where the denominator is larger (depending on STABILIZATION_ATTITUDE_SP_MAX_PHI).
This causes the euler setpoint to always be zero.

Closes #461
