I think these two regulators do not need boot-on?

Why not use mmc-pwrseq instead of rfkill?

Why not use shutdown-gpios of bcm43438-bt?

CLKOUT pin is not connected.

I recommend using clkm1_32k_out at the sdio-pwrseq node.

Maybe `brcm,bcm4329-fmac` nodes can be added here?

You can add `brcm,bcm43438-bt` nodes here:
bluetooth {
compatible = "brcm,bcm43438-bt";
device-wakeup-gpios = <&gpio3 RK_PC3 GPIO_ACTIVE_HIGH>;
host-wakeup-gpios = <&gpio1 RK_PC2 GPIO_ACTIVE_HIGH>;
shutdown-gpios = <&gpio1 RK_PC1 GPIO_ACTIVE_HIGH>;
...
};
Thanks,
