stmmac: Allow SOCs to use Store forward mode eventhough tx_coe is 0. (V2)

Browse Source 
This patch adds new field 'force_sf_dma_mode' to plat_stmmacenet_data
struct to allow users to specify if they want to use force store forward
eventhough tx_coe is not available in hw.
without this flag stmmac driver will use cut-thru mode not use
store-forward mode.
