    modules: factor out LinuxKPI based wireless drivers and add RISC-V
    
    The LinuxKPI based wireless drivers are currently limited to amd64 and
    arm64 (and until cleaned up i386).  Adding RISC-V now as we have a
    report that iwlwifi(4) works on RISC-V [1]. Factor the LinuxKPI based
    wireless drivers out into their own block.
    
    Given RISC-V has no ACPI support yet (though we fixed #includes in
    order to keep compiling the drivers without further modifications
    where possible) we need to take care of rtw89 which fails to compile
    without ACPI enabled.  A quick check at the Linux build files indicates
    that the depenency is not correctly recorded there either.  Disable
    compiling rtw89 without ACPI (on RISC-V) for the moment until this is
    fixed.
