bsps/stm32h7: workaround compilation issue with libbsd

Browse Source 
Part of the new HAL requires float_t type definition. For that it includes
math.h header file which unfortunately brings a lot of math functions in.
One of them, 'log' conflicts with FreeBSD log function defined in systm.h
Provided hack is really just a crude work around this issue. Never thought
that Motorola 68881 would help me even in 21st century.
