[PATCH 04/11] net: ethernet: stmmac: add management of stm32mp13 for stm32

[Christophe Roullier]

Add Ethernet support for STM32MP13.
STM32MP13 is STM32 SOC with 2 GMACs instances.
GMAC IP version is SNPS 4.20.
GMAC IP configure with 1 RX and 1 TX queue.
DMA HW capability register supported
RX Checksum Offload Engine supported
TX Checksum insertion supported
Wake-Up On Lan supported
TSO supported
