package/gnu-efi: mark as not supported on ARM soft-float

Browse source 
lib/print.c in gnu-efi contains some floating point computation. On
ARM soft-float configurations, these floating point operations
generate calls to __eabi_*() functions that are provided by
gcc. However, gnu-efi builds some freestanding code, so it doesn't
link with libgcc, and therefore the build fails with:

Since we don't care about gnu-efi support on ARM soft-float
configurations, let's disable such configurations.

Note that we have chosen to use BR2_ARM_SOFT_FLOAT as we're for now
making this specific to ARM as we're not sure what is the situation on
other CPU architectures (for example RISC-V without FPU maybe). This
can be revisited once we get more data on the behavior on other CPU
architectures that can support soft-float.
