[TF-M] Usage of TFM_SYSTEM_FP cmake variable

Hi everyone,

I have noticed that GCC toolchain uses CONFIG_TFM_FP to determine FP setting while IAR and Clang use TFM_SYSTEM_FP cmake variable. I was not able to find any docs on this variable, and also there is no assignment of this variable in TFM source code (only read operation from this variable).

Is this intendent behavior?
