possible add CONFIG define in dts?

hi all:
I want to share 1 dts when my linux kernel running on different platform.
is it possible to use #ifdef CONFIGxxx like below?
( Compile is pass, but I still get arm,data-latency, arm,tag-latency as <6 6 6>
Sincerely appreciate your kind help in advance,

        L2: cache-controller@ffe00000 {
                compatible = "arm,pl310-cache";
                reg = <0xffe00000 0x1000>;
                interrupts = <0 96 4>;
                cache-level = <2>;
#ifdef CONFIG_ARCH_PLAT_FPGA
                arm,data-latency = <0 0 0>;
                arm,tag-latency = <0 0 0>;
#else
                arm,data-latency = <6 6 6>;
                arm,tag-latency = <6 6 6>;
#endif
        };
