Subject: [PATCH] net: stmmac: Add additional registers for dwmac1000_dma ethtool

From: Thor Thayer <thor.thayer@...ux.intel.com>

Version 3.70a of the Designware has additional DMA registers so
add those to the ethtool DMA Register dump.
Offset 9  - Receive Interrupt Watchdog Timer Register
Offset 10 - AXI Bus Mode Register
Offset 11 - AHB or AXI Status Register
Offset 22 - HW Feature Register
