[PATCH] Kconfig/debug_uart: Enable proper drivers for debug on Zynq

[Olliver Schinagl]

When selecting CONFIG_DEBUG_UART_ZYNQ for one it is imperative that
CONFIG_SERIAL_ZYNQ is enabled. Further more, the zynq serial driver
is mostly?/all driver model based. However when compiling the early uart
for the SPL, none of that is available yet, so for the SPL build this
needs to be enabled also.
