This seems to be a recurring problem with this particular vendor kernel
unfortunately. Take a look at this patch which solves the same issue on
a different branch:
https://github.com/riscv/meta-riscv/blob/master/recipes-kernel/linux/linux-orangepi/orangepi-rv2/bcmdhd-fix-typedefs-header-not-found.patch

I think adapting this to your branch should solve your problem too.
