[PATCH u-boot v2019.04-aspeed-openbmc v2 2/4] arm/mach-aspeed: Add support for CONFIG_DRAM_UART_TO_UART1

[Patrick Rudolph]

Update the Kconfig and allow a board to use CONFIG_DRAM_UART_TO_UART1.
The platform code already uses this Kconfig symbol, but it always
evaluated to false.
This is required on IBM/Genesis3 as it uses RDX1/TDX1 as debug uart.
