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.
Tested for tftp and booting to kernel on am654-evm.

Changes in v4:
* Patch1 caused dra7 config build warnings corrected them.
Testing:
1) Build tested am3/4 and dra7. 2) Booted to kernel using cpsw tftp. arch/arm/dts/k3-am65.dtsi | 2 + arch/arm/dts/k3-am654-base-board-u-boot.dtsi | 170 ++++ configs/am65x_evm_a53_defconfig | 7 + drivers/net/ti/Kconfig | 8 + drivers/net/ti/Makefile | 1 + drivers/net/ti/am65-cpsw-nuss.c | 794 +++++++++++++++++++ drivers/net/ti/cpsw_mdio.c | 4 +- drivers/net/ti/cpsw_mdio.h | 2 +- 8 files changed, 985 insertions(+), 3 deletions(-) create mode 100644 drivers/net/ti/am65-cpsw-nuss.c
