[1/2] aarch64: ifunc rename for kunpeng and its default memcpy version

  Rename ifunc for kunpeng to kunpeng920, and modify the corresponding
function files including IS_KUNPENG920 judgement.

Also, we select __memcpy_falkor for Kunpeng by default.

Could you split this patch in two? One to add the Kupeng 920 default
memcpy and another one to rename the macro?
