ARM: zynq: Allow UART1 to be used as DEBUG_LL console.
The main UART on the Xilinx ZC702 board is UART1, located at address e0001000. Add a Kconfig option to select this device as the low-level debugging port. This allows the really early boot printouts to reach the USB serial adaptor on this board. For consistency's sake, add a choice entry for UART0 even though it is the the default if UART1 is not selected.
