arch/Config.in.arm: add FPU related options for ARMv8 cores
The ARMv8 cores have a mandatory FPU unit called FP-ARMv8, so we:
- add a new hidden Config.in option for the availability of this
unit (BR2_ARM_CPU_HAS_FP_ARMV8)
- allow the selection of a possible choice in the "Floating point
strategy", and add two new choices: BR2_ARM_FPU_FP_ARMV8 and
BR2_ARM_FPU_NEON_FP_ARMV8.
- specify the -mfpu values for BR2_ARM_FPU_FP_ARMV8 and
BR2_ARM_FPU_NEON_FP_ARMV8 cases, when used on ARM 32 bits (-mfpu
doesn't exist on ARM64, instead -mcpu modifiers are used, so they
will be added on a per-core basis).
