dt-bindings: net: dwmac: Validate PBL for all IP-cores

Indeed the maximum DMA burst length can be programmed not only for DW
xGMACs, Allwinner EMACs and Spear SoC GMAC, but in accordance with
[1, 2, 3] for Generic DW *MAC IP-cores. Moreover the STMMAC driver parses
the property and then apply the configuration for all supported DW MAC
devices. All of that makes the property being available for all IP-cores
the bindings supports. Let's make sure the PBL-related properties are
validated for all of them by the common DW *MAC DT schema.
