Merge tag 'arc-uart-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arc
Add support for DEBUG_UART on ARC devboards
This required us to do 2 things:
1) Insert a call to debug_uart_init() in early boot code
2) Convert serial_arc to Kconfig
Once both items above are done we just patched defconfigs.
