MIPS: ath79: make ath79_ddr_ctrl_init() compatible for newer SoCs
AR913x, AR724x and AR933x are the only SoCs where the ath79_ddr_wb_flush_base starts at 0x7c, all newer SoCs use 0x9c Invert the logic to make the code compatible with AR95xx Signed-off-by: Felix Fietkau <nbd@nbd.name> Cc: albeu@free.fr Cc: sergei.shtylyov@cogentembedded.com Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13257/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
