Add new driver for the TI AM65x SoC Gigabit Ethernet Switch subsystem (CPSW NUSS). It has two ports and provides Ethernet packet communication for the device and can be configured as an Ethernet switch. CPSW NUSS features: the Reduced Gigabit Media Independent Interface (RGMII), Reduced Media Independent Interface (RMII), and the Management Data Input/Output (MDIO) interface for physical layer device (PHY) management. The TI AM65x SoC has integrated two-port Gigabit Ethernet Switch subsystem into device MCU domain named MCU_CPSW0. One Ethernet port (port 1) with selectable RGMII and RMII interfaces and an internal Communications Port Programming Interface (CPPI) port (Host port 0).
Host Port 0 CPPI Packet Streaming Interface interface supports 8 TX channels and on RX channels operating by TI am654 NAVSS Unified DMA Peripheral Root Complex (UDMA-P) controller.

No new debug macros, use pr_err/etc directly and tweak CONFIG_LOGLEVEL / CONFIG_SPL_LOGLEVEL or the macro being used if things are now too spammy in real usage.

One usage of this function was clearly a bring-up debug print and for the other, we either call print_buffer on DMA failure or we don't care enough to. Thanks!
