[Patch AArch64 obvious] Unify address costs to generic_addrcost_table

Browse source 
The special case address cost tables for Cortex-A57 and qdf24xx are no
different from the generic address cost table. We should just use the
address cost table directly. If this changes in future, a core is welcome
to add new address cost tables.

gcc/

	* config/aarch64/aarch64.c (cortexa57_addrcost_table): Remove.
	(qdf24xx_addrcost_table): Likewise.
	(cortexa57_tunings): Update to use generic_branch_cost.
	(cortexa72_tunings): Likewise.
	(cortexa73_tunings): Likewise.
	(qdf24xx_tunings): Likewise.
