base: Force 60Hz refresh rate on boot with prop [1/2] 



[ SahilSonar - Murena ]
    FP5 device has a glitchy boot animation with peak refresh rate.
    This should be fixed the kernel/dtb, which is prebuilt from
    stock right now. This change introduces framework workaround
    that FP uses on their stock firmware which forces 60Hz during
    boot animation and switches back to user preference after boot.
    Also, added a prop check to avoid forcing this on other devices.
