Liming Sun 1357dfd726 platform/mellanox: Add TmFifo driver for Mellanox BlueField Soc
This commit adds the TmFifo platform driver for Mellanox BlueField
Soc. TmFifo is a shared FIFO which enables external host machine
to exchange data with the SoC via USB or PCIe. The driver is based
on virtio framework and has console and network access enabled.
