powerpc: Add CONFIG_PPC64_ELF_ABI_V1 and CONFIG_PPC64_ELF_ABI_V2
At the time being, we use CONFIG_CPU_LITTLE_ENDIAN and
CONFIG_CPU_BIG_ENDIAN to pass -mabi=elfv1 or elfv2 to
compiler, then define a PPC64_ELF_ABI_v1 or PPC64_ELF_ABI_v2
macro in asm/types.h based on _CALL_ELF define set by the compiler.
Make it more straight forward with a CONFIG option that
is directly usable.
