This commit introduces a Kconfig option for ARM SoCs, to signify that the SoC implements a double-precision floating point unit. The option is utilized in cmake/fpu-for-gcc-m-cpu to select the appropriate GCC compile option flag for FPU. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no>
