    nss-dp: switchdev: apply flag dependency directives
    
    The FDB roaming issues were observed on ipq807x and ipq60xx boards.
    The fix depends on API exposed only when NSS_DP_PPE_SUPPORT is enabled.
    However, this flag applies to above mentioned platforms only and is
    causing the logs to be flooded on other QCA platforms, including ipq50xx,
    with:
    
    [   34.893418] nss-dp 39c00000.dp1 lan: cannot get VSI ID for port 1
    [   34.898370] nss-dp 39c00000.dp1 lan: cannot get VSI ID for port 1
    [   34.904598] nss-dp 39c00000.dp1 lan: cannot get VSI ID for port 1
    [   34.910661] nss-dp 39c00000.dp1 lan: cannot get VSI ID for port 1
    
    So let's apply a dependency on the NSS_DP_PPE_SUPPORT flag and contain
    the patch code for ipq807x and ipq60xx within conditional directives.
    
    Tested on: Linksys SPNMX56
