Enabling this driver requires some DT changes.
Adding DCC to root or main bus:
dcc: dcc {
	compatible = "arm,dcc";
	u-boot,dm-pre-reloc;
};

Extend alias list to link DCC:
	serial0 = &uart0;
	serial1 = &uart1;
	serial2 = &dcc;

Change stdout-path to point to dcc port.
	stdout-path = "serial2:115200n8";

Also add support for debug uart to help with early debug.

In very very space-constrained devices even the full UART driver is too
large. In this case the debug UART can still be used in some cases.

Add options to enable the UART driver in SPL and U-Boot proper. Enable both
options by default.
